Pit Furnace Gas Nitriding Process Operation
1. Preliminary Treatment Determination Principle General structural steel parts are quenched and tempered. The high-temperature tempering temperature should be 20-40ºC higher than the nitriding temperature, and the holding time should not be too long. Normalizing can be used for parts with low im...
The Difference Between Hard Nitriding and Soft Nitriding
Hard Nitriding Nitriding is a type of chemical heat treatment, also known as nitriding, which refers to placing the workpiece in a nitrogen-containing furnace gas (ammonia-containing gas), selecting an appropriate temperature, gas flow, ammonia concentration ratio, etc., and maintaining it for a ...
Development of Debinding Technology
The origin of PIM technology can be traced back to the manufacture of ceramic spark plugs in the late 1920s, but the early development was very slow, and mass production and market did not form. CIMdebindingin the early 1940s and 1940s adopted the Bendix process. The main components of the binder...
Application of SPS Sinter in the Development of New Materials
Its typical applications mainly include the following type of materials . 1. Intermetallic compounds Intermetallic compounds can effectively utilize temperature brittleness and high melting point, so their preparation requires a special process. Using the SPS method to prepare intermetallic comp...
TC4 Solid Solution Water Quenching Heat Treatment Process
Titanium alloys can be divided into a titanium alloy, β titanium alloy and a+β titanium alloy according to their annealed state. Among them, a+β titanium alloy is the most widely used, and TC4 is a typical one. The main alloying elements of TC4 are AL and v, where AL is a stable a-phase element, ...
