Comparative study on vacuum nitriding and carburizing processes
Nitriding is a chemical heat treatment process that penetrates nitrogen atoms into the surface of the workpiece in a certain medium at a certain temperature. Commonly used are liquid nitriding, gas nitriding, and ion nitriding. Traditional gas nitriding is to put the workpiece into a sealed conta...
Introduction to vacuum brazing process of aluminum and aluminum alloys
Aluminum alloy liquid cooling plate With the widespread application of liquid cooling technology in various industries, there is a huge demand for aluminum alloy liquid cooling plates. Among the welding processes of various aluminum alloys, the brazing process occupies a very important position ...
Vacuum Furnace Brazing Process
Basic principles of vacuum brazing Brazing refers to a welding method in which the solder is melted by heating (above 450°C, but lower than the melting temperature of the base metal), and the capillary action of the liquid solder is used to fill the solder joint and mutually diffuse with the base...
Advantages of vacuum nitriding furnace for mold materials
Vacuum pulse nitriding furnace, vacuum nitriding furnace, referred to as nitriding furnace or nitriding furnace, is used for surface nitriding or nitrocarburizing of various aluminum molds, extrusion dies, screws, screw rods and other spare parts, especially suitable for There are nitriding treat...
Research on typical bearing vacuum heat treatment technology
Bearings used in automobiles are divided into two categories: sliding bearings and rolling bearings. Sliding bearings are mainly used on engines. Rolling bearings are widely used in various mechanical and electrical assemblies in automobiles. There are two types of rolling bearings, spherical and...
Plasma nitriding to enhance component performance
The demand for lighter and safer cars has driven the use of higher-strength steel grades for car bodies. Aerospace components have many of the same needs, but with more stringent control requirements for a wider variety of materials. Steel is now far stronger than it was in the past. Some automot...
Vacuum brazing liquid cooling heat sink plate
Nowadays, liquid-cooled heat sinks have become the preferred cooling method for various high-end electronic technology products, ranging from our common mobile phones and laptops to highly professional large-scale servers, laser cutting equipment, engines, wind turbines, etc. Whether it is a prec...
Effect of different post-weld insulation on vacuum brazing strength
PDC/45 steel brazing parts are widely used in cutting tools, oil drilling, coalfield geology, coal mine underground drilling construction and many other fields. During the vacuum brazing process of PDC tools, due to the uneven heating and cooling, as well as the constraints or external constraint...
Advanced vacuum high pressure gas quenching technology
1.High pressure gas quenching and its advantages After the workpiece is heated to the austenitizing temperature, 0.5 to 2MPa (5 to 20bar) high-pressure gas quenching is applied, which can achieve the quenching effect of static oil or high-speed circulating oil or even water. The gas quenching mec...
Process of vacuum heat treatment in aerospace industry
Vacuum heat treatment is a metal processing process that uses a vacuum environment to process metal materials. This treatment has many advantages, including the ability to increase material purity, reduce oxidation and contamination, and improve material performance. Vacuum heat treatment has wid...
