A MULTI-LAYER COMPOSITE INCLUDING A FLUOROPOLYMER SURFACE AND A NON-FLUORINATED POLYMER TRANSITION LAYER

摘要

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.
