Abstract
A bearing article can include a metal substrate having a bronze layer; a PEEK layer; a PTFE composition layer overlying and penetrating the PEEK layer. A method for preparing a bearing article can include providing a metal substrate with a sintered bronze layer, electrostatic spraying a non-fluorinated polymer onto the metal substrate followed by spraying a fluorinated polymer onto the non-fluorinated polymer and heat rolling to form a laminate.
Claims17
A method of forming a laminate, the method comprising:
- providing a metal substrate to which a layer of bronze particles is sintered;
- electrostatic spraying the metal substrate with a non-fluorinated thermoplastic powder comprising a ultra-high-molecular-weight polyethylene (UHMWPE), a polyimide (PI), a polyamide (PA), a polyamideimide (PAI), or any combination thereof, and covering the bronze particles with the non-fluorinated thermoplastic powder to form a transition layer;
- and
- spraying the transition layer with a fluorinated thermoplastic powder to form a compound layer, wherein the transition layer comprises PEEK, and wherein the fluorinated thermoplastic powder comprises polyvinylfluoride (PVF), polychlorotrifluoroethylene (PCTFE), a polyethylenechlorotrifluoroethylene (ECTFE), or any combination thereof.
