摘要：
A process for producing a crack-free, laser nitride-hardened layer on a titanium substrate, the process including preheating the substrate, melting a small area of substrate with a laser, and shrouding the melted area with a gas mixture having a maximum critical amount of nitrogen not greater than 85%. A crack-free pump shaft so hardened to Rockwell 52 C is produced.
