Dị ka n'ihe banyere nnukwu ego nke mgbakwunye, enwere ike ijikọta ya na ọkụ induction mgbe mmiri mmiri na-ekpo ọkụ na-arụ ọrụ na-ejikọta ya na nlebara anya, iji hụ na carburizer na oge mmịpụta mmiri nke 10Min, n'otu aka ahụ site na mmetụta mkpali electromagnetic nke carburizer zuru oke mgbasa absorption, iji hụ na mmetụta absorption. N'aka nke ọzọ, enwere ike ibelata ọnụọgụ nitrogen na-ebute n'ime carburizer.
Akwụsịla otu ugboro, gbakwunye na batches, ma mesịa gbazee akụkụ, tinye akụkụ nke ígwè ọkụ (ihe dị ka mkpọ) n'ime akpa ahụ, wee laghachi na carburizer ọkụ ugboro 1-2, wee slag, tinye alloy.
Enwere ọtụtụ akụkụ ị ga-aṅa ntị na:
