What is vacuum heat treatment processing technology?

Precision machined parts will have a certain degree of wear after assembly and operation. Heat treatment can enhance the hardness of the workpiece, increase the wear resistance of the workpiece and prolong the life of the workpiece. In this article, we will introduce to you what is vacuum heat treatment processing technology. Next week, we will introduce the characteristics of vacuum heat treatment. Welcome to continue to pay attention to our website blog.


Vacuum heat treatment is a metal heat treatment process in which the metal workpiece is heated below 1 atmosphere pressure (ie, under negative pressure). Among them, the vacuum environment in which the vacuum heat treatment is located includes low vacuum, medium vacuum, high vacuum and ultra-high vacuum.


Compared with conventional heat treatment, the vacuum heat treatment technology can realize no oxidation, no decarburization, and no carburization at the same time. Vacuum heat treatment can realize almost all heat treatment processes, such as quenching, annealing, tempering, carburizing, nitriding, gas quenching, oil quenching, nitrate quenching, water quenching, etc. Sintering, surface treatment, etc.


The process principle of vacuum heat treatment processing technology is to use the transformation characteristics of metal in vacuum state. Under the vacuum within the range of 0.1MPa difference from atmospheric pressure, the thermodynamics and kinetics of solid-state phase transformation do not change. At the same time, under the action of vacuum degassing, the physical and mechanical properties of metal materials can be improved. When heated in a vacuum state, elements on the surface of metal workpieces will evaporate. The vacuum degree required by the metal to achieve non-oxidative heating, the surface purification effect, and the realization of less and no oxidation and less dehydration.
