Because of this technology does not need the process of acid pickling and high temperature, there is no hydrogen embrittlement took place in the spare parts, and it possess a great deal of merits such as self-healing function after scotch, meanwhile it has hyper heat-resistance, hyper tonicity, hyper stickability, hyper anti-friction, hyper weatherability, hyper corrosion resistance, and when used outside, it can maintain its color for a long-period without change.

由于该工艺不经过酸洗和高温，所以零件无氢脆发生，擦碰伤后还有自愈合功能，同时还具有高耐热性，高渗透性，高附着性，高减摩性，高耐候性，高耐化学品腐蚀性。用在室外可长期保持不变色等诸多优点。

The fracture reasons of high strength PC steel wire are analyzed, it's considered that center segregation, central cavitation, poriness and inclusion are the metallurgical reasons which lead to the facture of PC steel wire and in the rolling process, differential coping quality, microcrack caused by surface defect, abnormal microstructure caused by burnt and improper cooling velocity, the ears on the head of the wire, overlapping of the wire rod itself are the main reasons which lead to the facture of PC steel wire. At the same time, inappropriate pickling, differential phosphorization quality, the bad heat treatment quality, the generation of crack in the improper drawing and transverse crack caused by abnormal laying of the drawing die are also the reasons of the cracking of PC wire.

对高强度PC钢丝断裂原因进行了分析，认为连铸坯的中心偏析、中心缩孔、疏松和夹杂是导致PC钢丝断裂的冶金原因；轧制过程中，较差的修磨质量、表面缺陷导致的微裂纹，过烧以及不适当的冷却速度导致的非正常显微组织，盘条头部的耳子、盘条本身折叠是导致PC钢丝断裂的主要原因；同时，不恰当的酸洗、较差的磷化及热处理质量、不适当拉丝裂纹的产生、拉拔模具安放不正导致的横裂也是PC钢丝断裂的原因。
