鎂鋁合金表面處理簡介

1、鎂鋁合金表面處理簡介Introduce the Surface Processing of the Alloy of Magnesium and Aluminum· 鎂鋁合金材質(zhì)特性· Characteristic of the alloy of MG and AL鎂是一種非?；顫娭?，相對的其材質(zhì)本身亦非常易生銹蝕，因此必須仰賴表面處理來保護(hù)其本身之材質(zhì)。MG is an active element ,it is more rustied than others. So it must depend on surface processing to protect i

4、omium series is the most universal process manner, also is the most stable and mature. Only does its materials have poison , it will be forbid to use. Its process flow refer to the diagram.（2）注意事項(xiàng)：注若需要表面涂裝時(shí)，請務(wù)必注意其涂裝制程是否有破壞到其表面之皮膜層，因其表面皮膜層最重要的是防止銹蝕，而其最重要的是當(dāng)作鎂合金與涂料之介質(zhì)使密著性會(huì)更好，因此涂裝時(shí)不能有破壞皮膜之現(xiàn)象發(fā)生。Remarks:

5、 If the surface need coating , please be sure to notice if the coating process damage the surface film. Because the surface film the most important is prevent to rustingb.檢驗(yàn)方式check manner：（1）電阻值：皮膜表面其電阻值，以三用電表檢測之。, examined by three-purpose galvanometer.（2）涂裝密著性：指皮膜處理后，再涂裝、以有格刮刀分割為100格并以3M610膠帶測試98%

6、以上，不能有剝落現(xiàn)象。Coating adhesion: it will not peel off coating again then cut 100 cross with a scraper and check 98% products with 3M610 adhesive tape after phosphating filming.（3）耐蝕性：以鹽霧測試機(jī)檢測皮膜層與涂裝層，最基本皮膜層必須超過24小時(shí)98%無腐蝕現(xiàn)象，而涂裝層則必須超過96小時(shí)以上98%無腐蝕現(xiàn)象，才視之為合格。Corrosion resistance:2.非鉻系皮膜處理與涂裝Phosphating filmin

7、g and coating of not chromium series其特性與鉻系是類似的，除了具有非毒性外其檢驗(yàn)方式與處理方式皆與鉻系相同，因此請參考鉻即可。The characteristic is similar with chromium series ; besides it is poisonous the manner of inspection and phosphating filming is the same with chromium series . so please refer to chromium .a.說明instruction：此項(xiàng)處理為最新發(fā)展之處理，

8、目前只有美國方面發(fā)展出來，電鍍材料本公司亦于83年12月完成配方，其特性是導(dǎo)電性非常好，電阻值可小于以下，并具有耐蝕性。Phosphating filming and coating of not chromium series is the newest process , now it is developed by America,the electroplate company finished the formula in December in 1983 ,its characteristic is having better electric conductivity,the ,

9、and it is corrosion-resistant.b.檢驗(yàn)方式check manner：（1）電阻值：鍍層表面電阻值以精密電表測之。, examined by accurate galvanometer.（2）密著性：以有格刮刀分割為100格，并以3M610膠帶測試，不得有剝落現(xiàn)象產(chǎn)生。Adhersion: it will not peel off coating then cut 100 cross with a scraper and check with 3M610 adhesive tape.（3）耐蝕性：以鹽霧測試機(jī)檢測鍍層，其至少要24小時(shí)以上鹽霧測試通過，才視之為合格。

10、Corrosion resistance:check cladding material with salt test machine , the test pass at least 24 hours later , then it is qualified .· 電鍍鉻處理Electroplated chromium processinga.說明：此項(xiàng)處理，是在電鍍鎳上面加上一層鍍鉻處理，可使鎂合金鍍件更加亮麗、美觀。a. instruction:the process is adding a tier of electroplated chromium on the elect

12、plated chromium on the electroplated nickel, it will make the electroplate of Mg alloy more valuable .b.檢驗(yàn)方式：與電鍍鎳相同。b. check manner : the same as electroplated nickels· 陽極處理與染色Plating and dyeinga.說明：鎂合金陽極處理其處理方式與鋁合金相似，只是藥水配方與整流器電流強(qiáng)度略有不同，此項(xiàng)處理目的在于防止銹蝕，但是不能導(dǎo)電，是屬于非導(dǎo)電之皮膜處理。a. instruction:the process

13、ing of Mg alloy plating is similar with Al alloys , only are medicinal liquid prescription and commutators current intensity a little different. The purpose of this processing is to prevent rusting .It belong to non-electric conduction phosphating filming because it can not conduct electricity.b.檢驗(yàn)方

14、式：check manner（1）染色密著性：以有格刮刀分割為100格并以3M610膠帶測試，98%以上不能有剝落現(xiàn)象。Dyeing adhesion: it will not peel off colors when cut 100 cross with a scraper and check 98% products with 3M610 adhesive tape after dyed.（2）耐蝕性：陽極處理之鹽霧測試，可依客戶要求來規(guī)定，但至少要有24小時(shí)以上，視產(chǎn)品之定之。Corrosion resistance: salt test of plating , maybe accor
