RASMUSSEN, Don, [Continued on next page] (54) Title: POWDER COATING COMPOSITIONS FOR REDUCING FRICTION AND WEAR IN HIGH TEMPERATURE HIGH PRESSURE APPLICATIONS (57) : The invention provides a powder coating composition comprising of thermoplastic polymers, ceramic particles, and cermet particles for lowering the friction coefficient, and improving wear and corrosion resistance of coated surfaces in high-temper- ature, high-pressure, and corrosive environ- ments. It also provides a method of coating application for improving adhesion of the coating to the substrate. The coating composi- tions are devoid of volatile organic solvents and can be applied on surfaces using thermal spraying, compression molding and other particle sintering approaches. A multilayer ar- chitecture consisting of an adhesive bottom layer and a non-adhesive, low friction top lay- er is disclosed. The coating can be used in oil and gas production and seawater injection. 20 15 10 E CO 0 CO -1.0 - 15 -.20 - 25 80 130 180 230 280 330 380 r- 0 0 x W O 20 17 /083 400 Al Temperature (°C) Fl a . 1 WO 2017/083400 Al MIDEDIM011010101110101111EM100111011101110VOIMIE SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, Published: GW, KM, ML, MR, NE, SN, TD, TG). — with international search report (Art. 21(3))
