Description

technical field [0001] The invention relates to a high-temperature nitriding treatment device, in particular to a high-temperature nitriding treatment device, and belongs to the technical field of nitriding treatment. Background technique [0002] High-temperature nitriding treatment refers to a chemical heat treatment process in which nitrogen atoms penetrate into the surface of the workpiece in a certain medium at a certain temperature. The products after nitriding treatment have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. Characteristics, aluminum, chromium, vanadium and molybdenum elements in traditional alloy steel materials are very helpful for nitriding. These elements form stable nitrides when they come into contact with nascent nitrogen atoms at the nitriding temperature, especially Molybdenum is not only used as an element to form nitrides, but also to reduce the brittleness that occurs at the nitriding tempe...

Problems solved by technology

But there is no alloy-containing carbon steel, because the nitrided layer formed is very brittle and easy to peel off, so it is not suitable for nitriding steel

[0003] High-temperature nitriding treatment is a heat treatment method for metals. It is a process in which ammonia gas and other gases used in nitriding are transported to the inside of the tank for nitriding reaction treatment. During the nitriding treatment, the tank may not be properly sealed The problem of tightness is easy to cause gas leakage, which not only affects the working environment. High-temperature gas is also prone to dangerous accidents. When nitriding heat-resistant steel and high-temperature alloys, the heavy metal quality will bring harm to the pick-and-place work. Inconvenient, during the nitriding process, the metal nitriding efficiency is slow, and it is not easy to fully contact with nitrogen, which affects the efficiency of nitriding treatment
