Reduced Chromium Powders
Applications:
· Target making by PM methods;
· Chromium coating by gas-flame or diffusion methods;
· Chrome aluminizing (a complex diffusion saturation of metal or alloy surface with chromium and aluminum to increase their heat and erosion resistance).
Powders are reduced from chromium oxide.
Two types of chemical composition exist: CrP1 and CrP2.
Powders are classified into 2 grain size types:
· S – standard-grain chromium powder (CrP1S, CrP2S);
· F – fine-grain chromium powder (CrP1F, CrP2F).
Powder grain size (base size):
· CrP1S, CrP2S 150 micron max;
· CrP1F, CrP2F 125 micron max.

Applications vary from metallurgy of heat–resistant superalloys, electrical engineering in compositions with copper, and deposition of thin films and functional coatings using PVD methods, to production of electronic components, large-format displays, tools, watch cases, household appliances, tinted glasses, car parts and accessories, machines and appliances, as well as others.
In thin-film deposition in vacuum by means of thermal evaporation electrolytic refined chromium is used in flake or granule form, by means of ion bombardment spraying or arc evaporation – in the form of various compacted products. For target production by powder metallurgy (PM) methods chromium ERCr in flake form is mechanically ground into MP-ERCr powder.
