Yes it can. We always need to consider part size, geometry, specifications etc. in making any decision but yes we can apply aluminium onto aluminium, or other metals onto aluminium

This is cold spray. In a nutshell: Take a metal powder particle... accelerate it to high speed using a supersonic jet stream ... and direct it where you want it ... then it will go SPLAT into the surface and stick! Next, do that with a spray of particles ... and now you're building up parts with Cold Spray. Titomic is mastering this technique across the alphabet of materials (like Titanium) with their Titomic Kinetic Fusion (TKF) process. TKF can be used for 3D printing of rockets, repair of thermally sensitive parts, bonding materials that can't be traditionally welded, specialised coatings ... many many applications.

Little behind🤔 I'm guessing you might be comparing this to traditional Spray Metal technology ?

Cold Spray is unique in its non-melt process, avoiding heat-affected zones, enabling the creation of thick coatings and precise geometry repairs with high bond strength. Metallisation and HVOF, while effective in their own right, involve melting and can affect the substrate thermally, generally producing thinner coatings and being less suitable for high-precision repairs.

The main difference is that cold spray isn't used for joining metals. It's perfect for restoring geometries and depositing coatings.

Absolutely - that's a perfect application for cold spray. In fact, it's used by Rolls Royce MTU for engine refurbishment to repair wear, pitting corrosion, and more. The best part is that it can apply corrosion resistant materials, such as aluminium, directly onto steel and other metals. It's also used as a grit blaster to remove corrosion. Flick the switch, and start fusing metal.

Can be done, but does depend on grade of steel

The process is based on Supersonic Particle Deposition, where the metal does not melt, not the base metal or the metal being sprayed. The gas is heated up and released through a De Laval nozzle which accelerates the metal powder in excess of 600 m/s, when it hits the surface it plastically deforms to become a solid metal without ever melting. This is a meltless process which is what provides it many of its unique benefits over melt-based processes.

That's incorrect, Michael. The process does not melt metals or use an electric arc.

@@DCPAus so is it only harder materials on to softer material's? How well is the bond does it withstand constant abrasion ? Of course to wear through as good as one could hope .

@@michaelvaughn7137 typically it is more ductile metals onto hard metals as that allows the metal powder to "splat" and then bond and build up. We are also able to blend hard materials together with softer metals to then create a good wear resistant surface

It does seem too good to be true but it definitely is real. The process is based on Supersonic Particle Deposition, where the metal does not melt, not the base metal or the metal being sprayed. The gas is heated up and released through a De Laval nozzle which accelerates the metal powder in excess of 600 m/s, when it hits the surface it plastically deforms to become a solid metal without ever melting. This is a meltless process which is what provides it many of its unique benefits over melt-based processes.

Certainly not a scam, Derrek! Check out this video demonstrating a 27kg titanium part manufactured in 4.5 hours. It works on the same principles, just with higher gas pressure and harder materials. ruclips.net/video/6-9xK08K2pc/видео.html

It's based on supersonic particle deposition. In short, we take compressed air and fire metal particles at the surface. As they collide, they plastically deform and mechanically bond together. That means we can spray different metals together without heat. Here's a video where James explains the process and benefits in more detail ruclips.net/video/B8amoLhNgz4/видео.html.

​@@titomiclimited is the bond affected by the starting surface texture? Is there an ideal surface texture i.e ground, bead blasted?

@@Storebrand_ ​ There are a number of factors affecting bond strength such as substrate material, material to be sprayed etc. If it is a production solution then we will define the solution with you including substrate preparation. If it is a field repair operation then we will always recommend a prepared surface. The system comes with two Powder Hoppers and we recommend loading one of the Hoppers with our Grit blast media, and then you can clean the substrate make sure it is free of oil, dust loose metal etc, switch hoppers (just a push of a button) and spray.

Maybe we could create a simple full timelapse of this.

Different metal powders have different deposition efficiencies (i.e. how much sticks) but as the powder is quite dense and its velocity drops off quite quickly the powder that does not bond is either sucked up by a dust extractor or falls to the floor. Titomic will work with clients to best define how to operate the system inside, whether a downdraft table is needed, whether an extraction is needed, make sure operators have the right PPE. When doing a simple demonstration though, as long as the operator is wearing the correct PPE it can all be handled safely with minimal mess or material loss.

The production time for a titanium valve using Titomic Kinetic Fusion technology significantly reduces the manufacturing timeline. Traditionally, such a component could take several weeks, considering the conventional processes involving casting, forging, and machining. Our state-of-the-art additive manufacturing process not only accelerates production but also minimises material wastage, providing a more sustainable manufacturing solution. The exact time can vary based on the complexity and specifications of the part being produced.

Thanks for the question! Common applications for the D523 include automotive remanufacturing for repairing worn or damaged parts, applying corrosion resistant coatings, and adding high-performance coatings for thermal and electrical conductivity. It's a versatile technology, so get in touch with us to find out where it can add value to your operations.

Generally, we would cut down to the crack, then fill with cold spray to prevent further propagation. Cold spray can be used for hermetic seals, and for re-sealing pressure vessels like you suggest. In fact, we even use our large scale systems to manufacture pressure vessels using this same process.

@@titomiclimited thank you... This is interesting technology

When surface prep is required, we use the same system to grit blast the surface, removing oxidation and contaminants. The system has two hoppers, which you can fill with different metal alloys, or grit blasting media. So the surface is prepared with grit blasting, then another hopper is selected, enabling metal to be sprayed.

@@titomiclimited It just gets easier all the time!

Hi Pazitor - thanks for the questions! It's exactly as you describe - another tool within the arsenal of a welder, fitter, machinist, or fabrication workshop. Compared to welding, the main benefit of cold spray is that it doesn't generate heat, meaning you can deposit thick coatings, up to 20mm, and restore geometries of shafts, keyways, and large sections in cast iron and other parts, meaning no more cracking, pre-heating, cooling, etc. So, in that regard, it does open up new opportunities to save more parts from the scrap heap, or for refurbishment work, enables operators to turn around parts more quickly, meaning more profitable operations. If you're interested, drop us an email at info@titomic.com. The team would be more than happy to chat.

Cast iron repair with iron or nickel or other hard metals - without heat! No cracking and no change to the base metal.

Hi there - it would certainly suit a rental period of a few weeks, where setup and training would be covered by the efficiency of the system. It takes less than a day to get acquainted with the system. This could be a great hardware addition to a rental provider. Feel free to get in touch with us at info@titomic.com if you'd like to discuss. Thanks.

Hi Roy - the D523 can apply coatings that are abrasion resistant to a degree. Please drop us a line at info@titomic.com if you'd like to have a chat with our technical staff.

Thank you! Cheers!

Thanks for the question! We're currently developing an entry-level model specifically for rim repair. Please drop us an email at info@titomic.com if you'd like to learn more. We'd be happy to have a chat regarding the options.

We will!

Hi Ace! It's a demonstrator of a pressure vessel, such as a propellant tank, created on one of our TKF 1000 systems.
