Abstract
The invention provides a method for producing bioinert biocompatible diamond particles/polymer composites or any other matrix (e.g. glass, metal, plastic, ceramic and more)/diamond particle composites, even if not biocompatible with outstanding mechanical, tribological, and biological properties, the method comprising selecting a polymer having a melting temperature below about 300 C; mixing diamond particles with the polymer to form a liquid mixture, poring the liquid diamond particle/polymer or any other diamond particle/matrix composite in liquid form into a mold and then causing the composite to sinter with the diamond particles densely and uniformly distributed through the bulk and surface of the composite, such that the diamond particles distributed on the surface can form a diamond layer covering the surface.
