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 … ਹੋਰ ਪੜ੍ਹੋ

How to Prevent Tungsten Carbide Corrosion

Development Status of Corrosion Resistant Cemented Carbides With the rapid development of industrial technology, people’s demand for materials is getting higher and higher. The materials used should have not only high strength, high hardness but also good corrosion resistance. For example, the chemical industry and machinery require materials to have good chemical stability, strong corrosion-resistance, but also high strength and hardness to withstand the dual effects of chemical corrosion and mechanical wear. Although there are many kinds of corrosion-resistant materials, However, the comprehensive indexes of hardness, strength and corrosion resistance make it imperative to study corrosion-resistant cemented carbides. Classification of … ਹੋਰ ਪੜ੍ਹੋ

Metal Powder Metallurgy in the Fabrication of Medical Instruments

Modern medical appliances are in great demand, and the structure of many medical appliances is also very sophisticated and complex, so a new manufacturing technology is needed to replace the traditional production. Nowadays, metal powder metallurgy can mass produce products with complex shapes in a short period of time, which can meet the manufacturing requirements of medical appliances and become an ideal manufacturing method. Metal powder metallurgy technology Metal powder metallurgy is a Near Net Shape Forming process developed rapidly in the 20th century. The general process is powder + binder mixing powder metallurgy degreasing sintering. The first is to … ਹੋਰ ਪੜ੍ਹੋ

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 … ਹੋਰ ਪੜ੍ਹੋ

5 Main Materials Applied in Cold Stamping Process

Stamping dies work under the impact, vibration, friction, high pressure, tension, bending and torsion loads, and even at higher temperatures (such as cold extrusion). The working conditions are complex and easy to be worn, fatigued, fractured, deformed and other phenomena. Therefore, the requirement for the material of the working parts of the die is higher than that of the ordinary parts. Due to the different working conditions of various stamping dies, the requirements for the materials of working parts of the dies are also different. Requirements for various stamping molds 1. for blanking dies High wear resistance and hardness are required … ਹੋਰ ਪੜ੍ਹੋ
