Elu plating dị iche na agba ya dị iche, oge nchekwa abụghị otu, nke ọ bụla nwere uru na ọghọm.
1. Zinc: ọdịdị ahụ bụ ọlaọcha na-acha ọcha, nwere ike ịbụ awa 12 ruo 48 nke nnu nnu, enwere ike ijikọta ya na ụfọdụ gluu (dị ka AB gluu), ma ọ bụrụ na mmetụta electroplating dị mma, enwere ike ịchekwa ya ruo afọ abụọ ruo afọ ise. , electroplating na-eri dị ala.
2.

3.

4. Black Nickel: na otu ihe ahụ chọrọ nke black zinc plating, bụ na ndabere nke nickel plating mgbe chemical ọgwụgwọ ịgbakwunye a oyi akwa nke nwa mmezi film.
5. Ọlaedo: a na-ejikarị ya eme ihe ịchọ mma ndọta, ugbu a enwere ọtụtụ ihe ịchọ mma aka magnetik ewu ewu.
6. Epoxy resin: iji tinye nguzogide nnu nnu na ngwaahịa ahụ, a na-agbakwunye akwa akwa resin n'èzí magnet mgbe nickel plating, nke na-abụkarị oji.Ọ bụ mkpuchi nwere ezigbo nguzogide corrosion n'èzí mkpuchi magnet.Ntuzi ndọta na imepụta n'usoro nke ndọta magnetik, nke pụtara bụ iji magnetize ihe ndọta ma ọ bụ enweghị ndọta ndọta iji tinye ndọta.N'ozuzu, ihe ndọta a ga-eme magnetized nwere ike idowe ya na ebe ndọta siri ike nke eriri igwe na-esi na ya na-esi na ya gafere, ebe magnetik dị n'ime magnet na-eme ka oghere magnetik na-eme ka ọ dị n'ime ya.
