Vacuum Hardening and Vacuum Tempering Heat Treatment for Metal Parts
Spring is an important part in various machinery and instruments. According to its use occasion and structural shape, it can be divided into two categories: leaf spring and coil spring. The type of steel used to make spring parts is called spring steel. Performance requirements of spring steel fo...
Practical Technology For Low Pressure Vacuum Carburizing Heat Treatment
The widespread application of vacuum heat treatment technology not only improves the performance of parts and products, but also promotes the rapid progress of its own process level and processing equipment. The current related key technologies continue to break through, the process is increasing...
Effects of Heat Treatments on Steels for Bearing Applications
1.Rolling bearings The characteristics of rolling bearings: easy use and maintenance, reliable operation, good starting performance, and high load-bearing capacity at medium speeds. Compared with sliding bearings, rolling bearings have larger radial dimensions, poorer vibration damping capabiliti...
Ceramic package shell vacuum brazing
A customer uses a hydrogen furnace to braze ceramic packaging shells. In dry hydrogen, the entire brazing process requires precise control of the dew point. At the same time, hydrogen will embrittle metals such as copper, titanium, copper, copper, and aluminum. , affecting the welding quality of ...
Production Process Of Vacuum Brazed Diamond Saw Blade
How to improve the holding power of diamond by the metal matrix has always been an important direction of research. Among them, the most commonly used method is to coat the diamond surface with Ti, Cr and other metals. Although diamond plating can effectively prevent thermal damage to diamonds an...
Heat treatment process for wide and thick plates
Introduction to heat treatment process of wide and thick plates Heat treatment uses different heating systems, holding times, and cooling rates to cause diffusion and recrystallization of the steel’s composition and structure. It can also promote or prevent the transformation and precipitat...
Vacuum brazing of aluminum alloys and filler metals
Because aluminum alloy has the advantages of light weight, good corrosion resistance, and good thermal and electrical conductivity, it is used in various sectors, and its usage is increasing year by year. It often appears in aerospace, construction, automobiles, ships and other fields, so it has ...
Effect of alloying elements on vacuum tempering of quenched steel
Alloying elements and strengthening and toughening of steel The main purpose of adding alloy elements to steel is to make the steel have better properties. For structural materials, the first is to improve To improve its mechanical properties, it is necessary to have both high strength and suffic...
Vacuum heat treatment of carburized steel parts
Performance requirements for carburized steel Carburized steel usually refers to the type of steel used after carburizing, quenching and low-temperature tempering. It is generally low-carbon high-quality carbon structural steel and alloy steel. The stress conditions of parts such as automobile an...
