磷化膜的主要功能
The main functions of the phosphating film
磷化加工主要用于鋼鐵工件表面處理,不但能作為*后的防腐層,而且還能當做中途的覆蓋層,他的主要用途有下面幾個方面
Phosphating process is mainly used in iron and steel workpiece surface treatment, not only can be used as the final coating, but also as the way of covering layer,
增強防銹能力,磷化層雖然比較薄,只有幾個微米,但是他是一種非金屬的不帶電的涂層,能把鋼鐵表面的優秀導體轉化為不導體,防止了鋼鐵件表面形成微小的電池,從而增加工件的防銹性能。
Enhance the capacity of anti-rust, although phosphate layer thin, only a few microns, but he is a non-metallic coating electrically neutral, can bring a good conductor on the surface of the steel into a conductor
磷化加工還能增強工件和涂層之間的結合力,使*外面的涂層不易脫落。磷化層和鋼鐵件是聯系在一起的,他們中間沒有顯眼的界限。磷化層伴有很多空隙,使得防銹油能滲透的里面。增強鋼鐵件的防銹能力。
Phosphating process can enhance the bonding force between the workpiece and the coating, make the most out of the coating is not easy to fall off. Phosphate layer and steel parts are linked together,
磷化處理能夠清潔工件表面。磷化加工前必須要把油和銹處理干凈才能生成,所以經過磷化加工的工件能帶來干凈,均衡沒有修飾的表層,使得工件在使用過程里不會生銹,起到了*終防銹的功能。
On the surface of the phosphating can sweep. Before phosphating process must clean the oil and rust treatment can be created, so after phosphating processing of the workpiece can bring a clean,
磷化層能提供材料冷加工的作用,比如磷皂化,拉絲磷化,冷擠壓。能提高工件的潤滑功能,冷加工磷化一般采用鋅系磷化為主,因為鋅系磷化后工件表層能形成潤滑性能很好的鋅膜,而且鋅系磷化一般溫度比較低。
Phosphate layer can provide material the effect of cold work, such as phosphorus saponification, drawbench phosphating, cold extrusion. Can improve the lubrication function,
磷化加工還能明顯改進工件的表層耐磨性能,使得工件表層的摩擦系數降低,以促進它的潤滑性能,常用作發動機活塞,齒輪,軸承等工件。錳系磷化膜具有較強的硬度,和耐磨性能。
磷化加工作用于工業制造行業已經有幾百年的時間,在這較長的時間中,磷化水平取得了突破性的進步。 |
