Quick preparation method of metal surface boronizing layer

Abstract

The invention provides a kind of superficial boronization level the fast preparation method. The method fast and the choice heats up and the acceleration chemical reaction characteristic using the microwave, in compares the low temperature and the short time intrinsic steel and iron and the metal surface preparation boronization level, it heating temperature may heat up compared to the electric stove reduces 100 DEG C about, heats up the time to reduce above three times, also the preparation boronization the level structure integrity, unifies with the substrate, the degree of hardness is high. The method broke through the traditional heat treatment to be unable in the low temperature, the short time obtained good infiltrates the level the limitation, had the significant industrial application value.

Description

technical background

[0001] The invention relates to a method for surface chemical heat treatment and microwave treatment, in particular to a rapid preparation method for a boronizing layer on a metal surface. Background technique

[0002] The preparation of metal material surface penetration layer has always been the most important means and method to expand the application range of materials and improve the corrosion resistance, wear resistance, heat resistance and other properties of materials, and has been widely used in industrialization, such as in molds, wearable parts and resistant Surface boronizing of parts used in corrosive environments. Therefore, the surface boronizing treatment of metal materials is a very effective material surface modification and protection method. The traditional method of boronizing the surface of metal materials is to place the metal material or the workpiece in the boronizing medium and keep it warm at high temperature for several hours...
