QPQ technology is a surface treatment technology which consists essentially of liquidnitriding and liquid oxidizing.
Q PQ技术是一种主要包括盐浴渗氮和盐浴氧化的表面处理技术。

Because the liquidnitriding the liquid and the work piece direct conduction heating, reduced the work piece heating-up time, raised the azotize speed.
液体氮化由于液体与工件直接传导加热，缩短了工件加热时间，提高了渗氮速度。

Two surface heat-treatment processes, liquidnitriding and sulfurizing, are used to compare with the current production process of liquid carburizing, with other variables remaining constant.
