Partial Protection of Ion Nitriding
There are many things to pay attention to when ion nitriding of parts. Ignoring them will bring difficulties to the operation and make it impossible to proceed, or the quality of nitriding does not meet the predetermined requirements, and more seriously may cause parts and equipment to be scrappe...
Introduction of Tools and Fixtures For Ion Nitriding
Generally, the ion nitriding process does not require tools or fixtures or only simple tools and fixtures. For example, when the gear is nitriding, it only needs to be directly placed on the cathode disk; the cylinder liner only needs to be placed on the cathode disk with three pillars underneath...
Nickel-based Solder
The best temperature performance can be obtained by brazing stainless steel with nickel-based brazing filler metal. When brazing with nickel-based solder, the size of the assembly gap has a great influence on the strength and plasticity of the joint, and a small gap means good performance. Take ...
Vacuum Brazing of Carbide Rotary File
Cemented carbide rotary files are mainly composed of high-hardness, refractory metal carbides (WC, TiC) micron powder, and cobalt (Co), nickel (Ni), and molybdenum (Mo) as the binder. Or powder metallurgy products sintered in a hydrogen recovery furnace. “Carbides, nitrides, borides, etc. o...
Factors and Prevention Methods of Ion Nitriding “Swelling”
The “swelling” of the parts after ion nitriding is actually a manifestation of the dimensional changes of the parts. The dimensional change is caused by the absorption of a large number of nitrogen atoms on the surface of the workpiece during nitriding, and the formation of various ni...
How to Prevent Heat Treatment Deformation of Precision Molds
We don’t want to see the deformation of precision and complex molds, but this situation is inevitable. We only need to grasp the law of deformation, analyze the causes, and adopt different methods to prevent mold deformation. Controllable. Usually, we can refer to the following methods for heat t...
The Influence Of Various Factors Of Vacuum Furnace On Product Quality
Vacuum is divided into physical vacuum and industrial vacuum two kinds.Physical vacuum refers to the space where no particles exist. Industrial vacuum refers to the gas space with pressure smaller than a standard atmosphere. It refers to the rareous gas state.The vacuum of vacuum furnace belongs ...
Introduction And Safe Operation Of Vacuum Heat Treatment Furnace
Vacuum heat treatment is a comprehensive technology combining vacuum technology and heat treatment, which means that all and part of the heat treatment process is carried out under vacuum.Vacuum heat treatment furnace thermal efficiency is high, can achieve rapid temperature rise and drop, can ac...
The Origin of Stainless Steel Wire Surface Quality and Heat Treatment
Heat treatment can improve the quality of the product. The surface quality of stainless steel wire is mainly determined by the pickling process after heat treatment. This article will talk about the relationship between the surface quality of stainless steel wire and heat treatment. 1. If the thi...
The Role of Preheating Before Welding and Heat Treatment After Welding
The welding of important components, the welding of alloy steel and the welding of thick parts all require preheating before welding. The main functions of preheating before welding are as follows: 1. Preheating can slow down the cooling rate after welding, facilitate the escape of diffusive hydr...
