磷化加工工艺主要用于汽车零部件,机械工业,五金电器,船舶制造业,航空航天工业,武器装备制造业等领域,在200多年的发展史中,磷化已经获得了很多新的成果。尤其是在汽车工业方面,取得了重要成果,磷化是汽车零部件加工,制造,防锈不可缺少的工艺。在很多表面处理技术中,磷化处理已经占据重要的地位。
Phosphating process is mainly used in auto parts, industrial machinery, hardware appliances, shipbuilding, aerospace, weapons and equipment manufacturing and other fields, in the 200 years of history, phosphating has received a lot of new achievements.
磷化加工是把工件放入包含磷酸,磷酸锰盐或者其他溶剂中,在特定的工作条件下,浸泡在磷化液中,工件表层产生化学反应和电化工反应,使工件表层产生具有防锈作用的锰系磷酸盐层即磷化膜。该磷化膜不但在工件防锈方面起关键作用,而且在工件耐磨自润滑,润滑,装饰方面也起到重要作用。
Phosphating process is put artifacts in the phosphoric acid, manganese phosphate salt or other solvents, under the condition of specific work, soaking in the phosphating solution, the workpiece surface produce chemical reaction and chemical reaction,
汽车覆盖件前处理技术中,绝大多数使用磷化技术。使用喷淋和浸泡相结合的技术,保护各种工件的处理。在最近研究成功的高温少渣的磷化技术中,使得能耗和磷化液消耗得到了较大降低,磷化是汽车防锈的关键。
Automotive covering parts before processing, most of the use of phosphating technology. Use spray and soaking with the combination of technology, to protect the processing of various artifacts.
航空航天装备需要磷化表层处理,使外观不受反光的影响,增加防锈能力和耐磨自润滑的效果,容易涂装。
Aerospace equipment need phosphating surface treatment, the appearance is not affected by reflective, increase the antirust capability and wear-resistant self-lubricating effect, easy to coating.
我们国家武器工业虽然磷化防腐工业应用近100年,虽有改进,但基本上还停留在20世纪六七十年代水准。主要是表面采用氧化发黑处理,耐磨防锈的技术远达不到实际应用需求,已经被其他表面处理技术所代替。
Arms industry in our country although phosphating anticorrosive industrial application for nearly 100 years, although have improved, but basically still stays in the sixties and seventies of the 20th century. |
