QPQ技术适用材料的范围广泛（QPQ technology applies to a wide range of materials）
QPQ技术适用于碳钢、合金结构钢、各类不锈钢、工模具钢、铸铁及铁基粉末冶金等材料。该技术可代替多种热处理工艺和防腐蚀工艺,如表面淬火、薄层渗碳、气体氮化、离子氮化、镀铬、镀镍、镀锌、发黑等工艺。
QPQ technology is suitable for carbon steel, alloy structural steel, all kinds of stainless steel, die steel, cast iron, iron-based powder metallurgy and other materials. This technology can replace many kinds of heat treatment and anti-corrosion processes, such as surface quenching, thin layer carburizing, gas nitriding, ion nitriding, chromium plating, nickel plating, zinc plating, blackening and so on.
