Why vacuum heat treatment is necessary
In modern life, we come into contact with a variety of metal products, such as steel bridges, car casings, kitchen knives, stainless steel guardrails, iron pots, cans, iron hammers, etc. In order for metal workpieces to have these properties that meet our different needs, in addition to selecting...
Introduction and principles of gas carburizing process
Introduction and principles of gas carburizing process Gas carburizing: It is a kind of metal surface treatment. Most of the carburizing methods are low carbon steel or low alloy steel. The specific method is to place the workpiece in an active carburizing medium and heat it to 900-950 degrees Ce...
Gas carburization techniques
The purpose of gas carburizing: Gas carburizing is to increase the carbon content and a certain carbon concentration gradient on the surface of steel parts. The chemical heat treatment process in which steel parts are heated and kept in a carburizing medium to allow carbon atoms to penetrate into...
Vacuum brazing technology of diamond tools
Diamond tools are divided into sawing tools, grinding and polishing tools, cutting tools, drilling tools, drawing dies, etc. Diamond sawing tools are divided into diamond circular saw blades, diamond gang saws, diamond wire saws, diamond wire saws, diamond inner hole saws, etc. according to their...
Research on powder metallurgy vacuum sintering of automobile transmission
With the rapid development of the automotive transmission industry, the requirements for gears as core components are also increasing. Requirements such as lightweight, low cost, low energy consumption, and new materials have become new challenges in its development. Advantages of powder metallur...
Research on Vacuum Low Pressure Carburizing Process
Although traditional atmosphere carburizing is currently widely used, it exposes many problems: oxidation within the workpiece; non-martensitic structure is difficult to avoid; large exhaust emissions; long carburizing cycle; workpiece is easy to oxidize and decarburize, etc. Compared with the tr...
Characteristics of vacuum carburizing technology
In the early stages of research and development of vacuum carburizing technology, it was not put into practical use due to carbon deposition problems. However, in 1997, a new technology of acetylene vacuum carburizing was developed to solve the problem of carbon deposition. Moreover, compared wit...
Effect of vacuum heat treatment on microstructure of alloy pipes
Clamp (Mo) has the characteristics of high melting point, high strength, high hardness, etc., and has excellent thermal conductivity, electrical conductivity, corrosion resistance and low thermal expansion coefficient. It is widely used in aerospace, metallurgy, nuclear energy, machinery, chemica...
Research on vacuum annealing of titanium alloys
The heat treatment of titanium alloy is a process that changes the phase composition and organizational structure of the alloy through heating, holding and cooling, thereby improving its performance. An important basis for determining the process parameters of titanium alloy heat treatment is the...
How does the vacuum sintering furnace work
Vacuum sintering furnace refers to a furnace that performs protective sintering of heated items in a vacuum environment. It has many heating methods. So, how does a vacuum sintering furnace operate? Vacuum sintering furnace operation process 1.Inspection before powering on Before turning on the p...
