Low Abrasion and Wear Coating
TriCom-706 is a “green” electro-composite coating consisting of a Co-P alloy metal incorporating SiC particulates which are uniformly dispersed throughout its matrix. TriCom-706 provides the best abrasion resistance among the TriCom family of coatings, having the lowest Taber Wear index (TWI). The TWI of TriCom-706 is similar to thermal spray WC, is lower hard chrome and substantially better than electroless nickel. TriCom-706 applications include suspension systems components for military vehicles and rotary engine components.
The TriCom coating is applied using an electroplating process similar to chrome but has a deposition rate 4X faster resulting in 1/5 the energy consumption and reducing CO2 emissions by the same. The part to be coated is held in a rack and immersed in an aqueous bath with electric current applied at the contact points.
Tank agitation keeps the 5-8 micron particles in suspension for uniform dispersion. The process is capable of coating net form shapes including external and internal diameters/surfaces. As with other electroplating processes TriCom tends to slightly build up on sharp edges and fade in deep corners. Embrittlement relief may be required for substrates exceeding 40 HRC.
- Exceptional abrasion resistance
- Applicable to Non-Line-of-Sight geometries
- Build-up/repair suitable to grind
- Heat treat for greater hardness to 900 HVN
- Corrosion resistant better than chrome
- Bonds to ferrous and non-ferrous metals
