SELF-LUBRICATED COATINGS OBTAINED BY THERMAL SPRAY METHODS

摘要

The present invention provides a method for preparing a coating comprising a matrix material and fluid filled capsules onto a substrate by using a thermal spray method. The method comprises applying the matrix material on the substrate by using athermal spray technique generating a flame or a jet. A liquid solution containing fluid filled capsules is simultaneously injected by a separate device into the flamefor obtaining homogeneously distributed capsules in the matrix. The separate device injecting the capsules inside the flame should allow full control on the exact injection position for avoiding the burning of the capsules and or the fluid. Consequently, the matrix material and the capsules are uniformly spread on the substrate, and thus, thecoating is obtained.
