Abstract:
     This penetration agent is a catalgtic activator to promate penetration of rare earth elements carbon-nitrogen trinary system on surface of metals in thermo-chemical treatment process. With this agent, the erosion resistance and anti-fatigue ability of the metallic surface increase markedly. Compared with conventional method, this agent is better in penetration velocity and technological stability. The preparation of this agent is simple, the raw material is abundant and the production cost is low.
