Abstract
A composition for coating sliding or rolling or fretting or impacting members is formed by preparing a composite powder of TiB2 and BN, with a TiB2 to BN ratio ranging from 1:7 to 20:1, and a metallic matrix selected from the group consisting of nickel, chromium, iron, cobalt, aluminum, tungsten, carbon and alloys thereof.
Claims18
A coating composition for use on a contact surface, comprising 5 to 60 wt % total of composite powder having an average primary particle size ranging from 1 to 1000 μm, the balance comprising (i) a matrix-forming metal, metal alloy or high-temperature polymer, and (ii) a binder chosen from an acrylate resin, a methacrylate resin, a thermally cured phosphate binder, a thermally cured potassium silicate binder, or mixtures of two or more thereof;
- wherein the composite powder comprises TiB2 and BN in a ratio of BN to TiB2 of 1:7 to 20:1.
A coating composition for use on a contact surface, the composition comprising:
- a compound powder mixture comprising a metallic matrix selected from the group consisting of nickel, chromium, iron, cobalt, aluminum, tungsten and alloys thereof, a binder chosen from an acrylate resin, a methacrylate resin, a thermally cured phosphate binder, a thermally cured potassium silicate binder, or mixtures of two or more thereof, and a composite powder of TiB2 and BN;
- wherein the metallic component is present from 40 to 95 wt. % of the final coating composition and the TiB2 to BN ratio in the composite powder of TiB2 and BN is in the range of 1:7 to 20:1.
