Ọgwụgwọ dị n'elu maka mkpuchi laser 

Teknụzụ mkpuchi laser bụ teknụzụ mgbanwe elu ọhụrụ nke pụtara na 1970 site na mmepe nke lasers ike dị elu.Ọ pụtara na teknụzụ mkpuchi elu nke laser bụ mkpuchi elu nke a na-etolite site na ikpo ọkụ ngwa ngwa na agbaze alloy ma ọ bụ ntụ ntụ seramiiki nke nwere ihe dị n'elu ala n'okpuru ọrụ nke osisi laser, wee nwee obi ụtọ n'onwe ya mgbe ewepụrụ osisi ahụ iji mepụta mkpuchi elu. na oke dilution ọnụego na metallurgical bonding na mkpụrụ ihe.Nke a bụ usoro na-ewusi elu elu nke na-eme ka ọnyà na-eguzogide, nkwụsị corrosion, nguzogide okpomọkụ, nguzogide oxidation na njirimara eletriki nke elu ala.

Dị ka ihe atụ, mgbe laser cladding nke tungsten carbide na 60 steels, ike na-eru 2200 HV ma ọ bụ karịa, na eyi na-eguzogide bụ ihe dị ka ugboro 20 nke isi 60 ígwè.Mgbe mkpuchi laser nke CoCrSiB alloy n'elu igwe Q235, a na-atụnyere nguzogide iyi ya na nguzogide ire ọkụ nke ịgbasa ọkụ, ma chọpụta na nke mbụ dị elu karịa nke ikpeazụ.
