1. Basic knowledge of cemented carbide
Q1: What is cemented carbide?
A1: Cemented carbide is a composite material composed of refractory metal carbides (such as tungsten carbide, titanium carbide, etc.) and metal binders (such as cobalt, nickel, iron, etc.). These components are sintered at high temperatures using powder metallurgy methods, resulting in extremely high hardness, wear resistance and compressive strength.
Q2: What are the main application areas of cemented carbide?
A2: Cemented carbide is widely used in cutting tools, drilling tools, wear-resistant parts and other fields, especially in machinery manufacturing, automobile manufacturing, aerospace, electronics industry, petrochemical industry and other industries due to its high hardness and high wear resistance. Sex makes it an indispensable material.
2. Performance characteristics of cemented carbide
Q3: What are the physical properties of cemented carbide?
A3: Cemented carbide has physical properties such as high hardness, high wear resistance, high compressive strength and good thermal stability. These properties allow it to maintain good performance under high temperature, high pressure and harsh environments.
Q4: What are the advantages of cemented carbide compared with high speed steel?
A4: Compared with high-speed steel, cemented carbide has higher hardness, better wear resistance and higher cutting speed, which can significantly improve the service life and processing efficiency of tools.
3. Preparation and use of cemented carbide
Q5: What are the preparation methods of cemented carbide?
A5: The preparation methods of cemented carbide mainly include powder metallurgy and solution infiltration. The powder metallurgy method is formed by mixing carbide powder with a metal binder, pressing it, and then sintering it at high temperature; the infiltration method is to obtain cemented carbide by infiltrating metal.
Q6: What should you pay attention to when using cemented carbide?
A6: When using cemented carbide, attention needs to be paid to maintaining the sharpness of the tool to avoid excessive wear; at the same time, appropriate cutting parameters and coolant must be selected to ensure the processing effect and tool life.
