1前言金属磷化处理现已为人们所熟悉,并已在工业中大批应用这类工艺,可以改变金属表面所具有的性质,而提供新的物理特性和物理化学特性,在许多化学表面转化处理工艺中,磷化占有重要地位。这是因为磷化处理工艺简单容易操作,成本低廉,用途广泛。所以,普遍应用于机械,汽车,航空,造船等工业以及家庭日用品制造工业等方面。磷化处理工艺应用于工业中已有80年历史,在
1 Introduction Phosphating metal phosphating is now well known and has been used extensively in industry to modify the properties of metal surfaces and to provide new physical and physico-chemical properties. Many chemical surface conversion treatments Phosphorization plays an important role in the process. This is because the phosphate treatment process is simple and easy to operate, low cost, wide range of uses. Therefore, widely used in machinery, automotive, aviation, shipbuilding and other industrial and household goods manufacturing industries. Phosphating process used in industry for 80 years, at
