Vacuum brazing process of nickel-based mixed brazing filler metal
Vacuum brazing of 316L stainless steel with nickel-based mixed brazing filler metal. Technological test research was carried out on it, and by means of metallographic imaging microscope, scanning electron microscope, energy spectrum analysis and microhardness analysis and other modern testing met...
High Pressure Gas Quenching Technology For Gears
Vacuum high pressure gas quenching and its advantages After the workpiece is heated at the austenitizing temperature, 1~2MPa high-pressure gas quenching can achieve the quenching effect of static oil or high-speed circulating oil or even water. The gas quenching of the workpiece is different from...
Heat treatment of involute spline parts realized by vacuum oil quenching technology
With the continuous expansion of the automobile market, the processing requirements for various types of parts are also getting higher and higher. Vacuum heat treatment has the advantages of high quality, low energy consumption, no pollution (or less pollution), etc. It can effectively prevent de...
Garment cutting machine high speed steel straight blade vacuum heat treatment
The garment manufacturing industry has developed rapidly in recent years. After China’s entry into the World Trade Organization, garment exports have continued to expand and product styles have increased, and the garment industry has achieved considerable development. With the continuous im...
Six details of gas carburizing
Gas carburizing is one of the most widely used chemical heat treatment methods. Everyone is very concerned about the three basic processes of decomposition, absorption and diffusion, as well as carburizing temperature, strong infiltration time, carbon potential in different periods, furnace press...
Control of retained austenite in tooth angle by vacuum carburizing heat treatment
Retained austenite (Ar) refers to austenite that does not undergo martensitic transformation under a certain degree of undercooling. The amount of retained austenite, the range of martensitic transformation start temperature (Ms ) and end temperature (Mf ) relative to room temperature, the chemi...
Vacuum brazing of surgical forceps – heat treatment process
The needle holder is a surgical instrument used for holding suture needles and knotting. The working end needs to be inlaid with cemented carbide by inlay technology to obtain better wear resistance, anti-skid performance and easy maintenance and replacement. In recent years, the vacuum brazing h...
Tips for vacuum brazing problem
a) The product is not melted 1.Phenomenon and reasons: It refers to the fact that a small part of the product in the furnace is not melted during the normal process of brazing, which is called the product is not melted. 2.Solution: Unmelted products mainly include: (1) The operator’s door ...
Research on Vacuum Heat Treatment Technology of Cr12 Steel
Cr12 steel is one of the widely used cold work die steels. The steel has the advantages of good hardenability, high hardness, wear resistance, and small heat treatment deformation. It is often used to make cold work dies that bear heavy loads, large production batches and complex shapes, such as ...
Vacuum heat treatment of 3Cr2W8V steel-aluminum die-casting mold
Die casting is the abbreviation of pressure casting. It is a method of filling liquid or semi-liquid metal in the die-casting mold cavity at high speed under high pressure, and rapidly solidifying under pressure to obtain castings. The die-casting mold used is called a die-casting mold. The commo...
