[0002] Quenching is a heat treatment process, which refers to the process of heating steel, aluminum alloy, copper alloy, titanium alloy, tempered glass and other workpieces to above the critical temperature, keeping them warm for a certain period of time, and then cooling them at a rate greater than the critical cooling rate. Commonly used quenching media include brine, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces, and is therefore widely used in various tools, molds, gauges and parts that require wear-resistant surfaces.
