QPQ鹽浴氮化方面的內(nèi)容作者: hwhuo 時間: 2009-12-21 14:23
Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance, originally developed by the Kolene Company. The name refers to the three steps involved: nitrocarburizing, polishing, and post-oxidizing.[1]3 A- [' [( l: R
/ Q# Y" {! b3 z: nThis process is usually used when two or more of the following properties are required in a workpiece: wear resistance, corrosion resistance, lubricity, or fatigue strength. However, it is also used when superior corrosion resistance is required. Common applications are piston rods for shock absorbers, cylinders and rods for hydraulic systems, pumps, axles, spindles, and valves.[2]6 v% i8 { K$ c/ N

看過上述,，可知道 QPQ 是quench polish and quench 的縮寫。具體工藝是碳氮共滲,，拋光和后處理三步,；主要目的是提高耐磨性，增強(qiáng)防腐能力,，提高潤滑性和抗疲勞能力等,。
