Shenzhen Su's heat treatment of 40Cr steel auxiliary views hollow cathode ion nitriding

Editor：    Date：2014-08-22 16:22:47    Views：3523

(1) hollow cathode ion nitriding technology can effectively Nitriding on the workpiece, can avoid generating arc and damage the test piece surface smooth degree of danger.
(2) hollow cathode ion nitriding technology at very low pressure (100~150Pa) of nitriding case, reduces the use amount of ammonia. To save energy, reduce pollution.
(3) hollow cathode ion nitriding technology, the sample can be neutral, surface strengthening processing of 40Cr steel, under the optimum conditions, the thickness of compound layer is about 2um, the thickness of the nitrided layers can reach 200um, the surface hardness is two times higher than the body.
(4) 40Cr steel hollow cathode ion nitridation, the most suitable processing temperature should be 500 ℃, the most suitable time of treatment should be about 6H.

Austenitic stainless steel under different heat treatment techniques for the performance of the different resistance corrosion and wear resistance
Austenitic stainless steel under different heat treatment techniques for the performance of the different resistance to corrosion and wear properties of a great relationship: the number and morphology of precipitates in the pure wear conditions, no corrosion, material quality loss is influenced by mechanical factors.
Vacuum heat treatment of the problem
Vacuum heat treatment processing, the processing surface of the product is often a problem, "colored" areas appear. Obtain appearance of bright, no coloring effect is the common goal of product processing vacuum furnace manufacturers and users to pursue research and development.
Vacuum heat treatment technology to resolve
Comprehensive technology of vacuum heat treatment vacuum technology and heat treatment technology of two professional combination, refers to the heat treatment process of all or part of the vacuum condition. Is generally believed that the vacuum furnace is divided into high, high, medium and low vacuum.
Factors that affect the performance of the heat treatment
Today su shi heat treatment come to you of what the factors in the use of vacuum heat treatment furnace heat treatment will affect the performance of the heat treatment:

1
