Fabrication and anti-ablation performance of W/Cu composite coatings by SAPS

摘要

Tungsten/copper(W/Cu)composites,which combine the high thermal property of Cu and the low expansion and high melting point characters of W.At high temperature,Cu phases has low melting point and high boiling point,it can be used for removing heat from the engine components by a mechanism like sweating,which is beneficial to improving the anti-ablation property.Thus,applying W/Cu coating opens up a new way to increase the anti-ablation ability of C/C composites[1].
