Characteristics and Application of Common Bearing Materials

As we all know, there are many kinds of bearing materials in the market. There are three kinds of common bearing materials: metal materials, porous metal materials, and non-metamaterials. Table of Contents Metal MaterialsBearing alloycopper alloyAluminum-based alloyGrey cast iron and wear-resistant cast ironNonmetallic MaterialsPorous Metal Materials Metal Materials Bearing alloys, bronze, aluminum-based alloys, zinc-based alloys, etc. are all metal materials. Among them, bearing alloys, also known as white alloys, are mainly alloys of lead, tin, antimony or other metals, which have low strength under heavy load and high-speed conditions. The reason is because of its characteristics, such as good wear resistance, … Read more


Quenching crack is a common quenching defect, which is caused by many factors. Because the defects of heat treatment begin with product design, the work of preventing cracks should start with product design. It is necessary to select materials correctly and design structures rationally, put forward appropriate technical requirements for heat treatment, properly arrange technological route, select reasonable heating temperature, holding time, heating medium, cooling medium, cooling method and operation mode, etc. Table of Contents Material aspectStructural Design of PartsTechnical Conditions for Heat TreatmentQuenching CrackForging cracks Material aspect 1. Carbon is an important factor affecting quenching tendency. With the increase … Read more

Application of Scanning Electron Microscope in Material Analysis

Since the first commercial scanning electron microscope came out in 1965, after 40 years of continuous improvement, the resolution of scanning electron microscopy has increased from 25 nm of the first one to 0.01 nm. Most scanning electron microscopy can be combined with X-ray spectrometer and X-ray energy spectrometer, which has become a comprehensive analysis of the surface micro-world. Multifunctional electron microscopy instrument. Scanning electron microscopy (SEM) has become a powerful tool widely used in various scientific fields and industrial sectors. Scanning electron microscopy (SEM) has been widely used in many fields, such as geology, biology, medicine, metallurgy, mechanical processing, … Read more

How do Grinding Parameters Impact on Tungsten Carbide Products?

Hey everybody, a new material weekly on surface grinding of ultra-fine cemented carbides. Reading this probably cost you about 15 minutes Abstract of this article: The grinding experiment of superfine cemented carbide was carried out on a plane grinder with diamond grinding wheel. The grinding surface morphology was observed by scanning electron microscopy and the surface roughness was measured by surface roughness tester. The influence of grinding parameters on the surface roughness of ultra-fine cemented carbide grinding was analyzed. The results show that the grinding surface roughness of superfine cemented carbide increases with the increase of grinding wheel size at the same … Read more

What Should You Know about Brazing of Carbide Brazed Tools

The main products that need to be used for brazing carbide brazed tools are the bimetallic structure of cutting tools, measuring tools, dies and excavation tools. The characteristic of this bimetallic structure is that its cutting parts are cemented carbide, and the matrix is carbon steel or low alloy steel, usually medium carbon steel. A bimetallic structure can cushion the tremendous stress acting on this kind of workpiece, especially under compressive bending, impact or alternating loads. Most of the carbide brazed tools are welded to the medium carbon steel or low alloy steel matrix. The brazing process is closely related … Read more
