PHNi-60A合金粉末是我厂生产的产品,是在Ni-Cr-Si系自熔性合金中比较典型的粉末喷涂材料。它具有自熔性好、高硬度、耐磨、耐蚀腐的特点。因此,多年来已被广泛应用于柱塞类产品的修复及预保护。经多年的推广应用,在石油压裂车柱塞,泥浆泵柱塞,抽油泵柱塞,采金船油缸柱塞等系列进口产品的修复及制造中已经取得了显著的经济效益,解决了过去花昂贵外汇,订货周期长的难题。经过用PHNi-60A粉末喷焊工艺处理过的柱塞,其机械性能得到了改善,使用寿命得到了不同程度的提高。不但节省了原材料的消耗,而且减少了检修时间,提高了作业率。本文仅对用于柱塞系列的PHNi-60A涂层的宏观力学性质及微观结构进行初步的分析研究。
PHNi-60A alloy powder is produced by our factory and is a typical powder coating material in Ni-Cr-Si self-fluxing alloy. It has good self-melting, high hardness, wear-resistant, corrosion-resistant characteristics. Therefore, over the years has been widely used in plunger repair and pre-protection products. After years of popularization and application, it has obtained remarkable economic benefits in the repair and manufacture of series of imported products such as petroleum fracturing truck plunger, mud pump plunger, pump plunger, Spend expensive foreign exchange, ordering a long period of problems. After PHNi-60A powder spray welding process of the plunger, its mechanical properties have been improved, the service life has been improved to varying degrees. Not only saves the consumption of raw materials, but also reduce the maintenance time and improve the operating rate. This article only for the PMAi-60A series of plunger macroscopic mechanical properties and microstructure for preliminary analysis.
