Classification of surface heat treatment

Surface heat treatment technology can be roughly divided into three categories: overall surface heat treatment, surface heat treatment and chemical surface heat treatment. The same metal chooses different surface heat treatment technology, which can achieve different arrangements, and then has different functions. Let's analyze the specific problem specifically to see what three methods of surface heat treatment are

Principle of vacuum nitriding treatment

Gas nitriding generally uses anhydrous ammonia (or ammonia + hydrogen, or ammonia + nitrogen) as the nitrogen supply medium. The entire nitriding process can be divided into three stages

Classification and hardness testing methods for heat treatment plants

The hardness of the heat treated workpiece is tested by a hardness tester. PHR series portable surface Rockwell hardness tester is very suitable for detecting the hardness of surface heat treatment workpieces, and can test various surface heat treatment workpieces with an effective depth of more than 0.1mm. Simple operation, easy to use, low price, can directly read the hardness value
