Process deposits variety of metals
Kinetic Metallization is capable of depositing fully dense, adherent coatings of a variety of metals on standard metal surfaces without costly surface preparation.
Inovati has just been awarded an R and D 100 award for 2002 from R and D Magazine for the development of equipment and processes for its low-temperature metal deposition technique, Kinetic Metallization (KM) KM is capable of depositing fully dense, adherent coatings of a variety of metals on standard metal surfaces without costly surface preparation

Coatings of pure copper, stainless steel, nickel, chromium, aluminum, cobalt, titanium, niobium, and other metals, as well as alloys based on these metals are possible on such surfaces as steel, aluminum, titanium, copper, brass, etc.
Additionally, braze powders (e.g., silver, copper, aluminum or nickel-based) can be sprayed out onto parts to be joined and coatings have also been demonstrated on ceramic substrates.
The feedstock material for KM is powder.
The cost of KM is comparable to competitive processes.
Applications include the preparing of corrosion and/or wear-resistant surfaces for parts, machinery and equipment.
Electrically conductive and decorative coatings are also deliverable.
Since the powders are deposited at well below their respective melting points, the coatings exhibit very fine grain size and one can avoid heat distortion of the workpiece being coated and interdiffusion of multi-layer coatings.
Spray forming of such metals as pure aluminum and Al-SiC composite has also been successfully carried out with fine microstructure in the final material.
Inovati is set up to both contract coat and to sell spray-coating equipment and consumables for KM.
One successful application has been the spraying of aluminum grounding strips on steel telecommunications equipment racks made by Hendry Telephone Products.
Inovati has received federal R&D contracts from the Ballistic Missile Defense Organization (BMDO), US Army, and US Navy.
In addition, the Australian Navy recently tested a KM-sprayed aluminum coating on a Mg alloy, which showed excellent salt-fog corrosion resistance up to 168 hrs.
compared to 12 hrs.
for a standard chromate coating.
Other applications can include replacement of organic plating (e.
g., hexa-valent chrome).
