Surface treatment hi base material atanga mechanical, physical leh chemical property hrang hrang hmanga base material chunglama surface layer siam dan tur process method a ni. a tum ber chu corrosion resistance, wear resistance, decoration emaw special functional requirement dang emaw a siam a ni a, chu chu metal castings atan a ni a, surface treatment chuan deep layer chu workpiece surface-ah nghet taka a inzawm tir thei a, chu chu product-a service life sang tak a nih loh chuan, leh a nih loh chuan, leh a nih loh chuan, a hlawhtling thei ang. Enkawl a nih chuan, coating leh metal-a bonding strength leh corrosion resistance a nghawng mai bakah, base metal chu a chhe chhunzawm zel bawk a, chu chuan coating peeling a thlen a, workpiece-a mechanical property leh service life a nghawng a ni.
Metal castings atan chuan kan hman tlanglawn zawk surface treatment methods te hi mechanical grinding, chemical treatment, surface heat treatment, leh spraying surface. surface treatment chu workpiece chunglam chu tihfai, sweep, deburr, degrease, leh deoxidize tur a ni.
Workpiece processing, transportation leh storage lai hian surface hian oxide scale, rust, mold sand, welding slag, dust, oil leh thil dang bawlhhlawh te a keng tel fo thin. chu coating chu workpiece surface-a nghet taka a inzawm theih nan, workpiece surface chu painting hmaa tihfai a ngai. Chutiang a nih loh chuan, coating leh corrosion-a insumna, corrosion resistance chu a nghawng mai mai dawn lo a ni. Coating protection nen, coating chu a peel off tir a, chu chuan workpiece-a mechanical property leh service life a nghawng a ni. Chuvangin, painting hmaa workpiece surface treatment chu guarantee pawimawh tak a ni a, chu chu high-quality protective layer hmuh theihna tur leh product-a service life tihzauh nan a ni.
