各種材料在不同的環境作用咸陽生產熱噴涂技術下，時間久了就會被氧化腐蝕，這是一種正常的自然現象。即使是金屬，也一樣會被腐蝕。有一些具有金屬材料的機械設備，腐蝕損壞會造成性能下降的后果。為了避免這種狀況的發生，就會給一些金屬的材料做金屬噴涂，以此來保護金屬不被氧化。下面也是簡單給大家分享一下金屬噴涂過程。 咸陽生產熱噴涂技術的工藝流程(cheng)：預(yu)處理→噴(pen)涂(tu)→干燥。預(yu)處理是使涂(tu)膜(mo)附著力強、不(bu)(bu)易脫落、壽命長(chang)，噴(pen)涂(tu)前必須對零(ling)(ling)件表面預(yu)處理。不(bu)(bu)同的金屬材料零(ling)(ling)件預(yu)處理方法(fa)不(bu)(bu)盡相同。
