Tungsten Oxide

Tungsten coating is mainly used in aviation, aerospace, nuclear power, machinery and other industrial fields, and the key parts of friction and movement parts wear protection. Tungsten coating is difficult to prepare because of its special properties. The basic process of high explosive loading spraying technology can be divided into three stages: 1. The use of explosive detonator is paved on the surface of the powder coating with explosives, explosive detonation wave propagation in detonation, similar to slip in explosive welding of detonation wave, high temperature and high pressure of the detonation product formation; 2. The powder of flying coating moves rapidly downward under the action of detonation wave and detonation products with high speed expansion, which can reach a higher speed. By selecting the type of explosive reasonably, controlling the distance between coating powder and matrix, the target velocity of coating powder can be controlled effectively, and the best velocity...
