Kedu ihe bụ elu ugboro quenching?
Quenching bụ ụdị ọgwụgwọ okpomọkụ, gụnyere nkwụsị izugbe, nkwụsị nke pulse na quenching isothermal.
N’ozuzu, quenching na-eme ka workpiece nwere ụfọdụ microstructure iji hụ na a ụfọdụ ngalaba osobo chọrọ n’ibu Njirimara mgbe tempering. Nwere ike melite ike na ike; mụbaa iguzogide iyi.
Pulse quenching bụ ikpo ọkụ na workpiece n’ime obere oge (dị ka 1/1000 nke abụọ) site n’enyemaka nke ike dị elu nke usu, ma mee ka ọ dị jụụ ngwa ngwa, nke nwere ike nweta mkpụrụ ọka dị oke mma na isi ike dị elu, enweghị nrụrụ. ọ dịghị ihe nkiri oxide, eyi na-eguzogide ọgwụ na corrosion na-eguzogide.

Austempering bụ ikpo ọkụ workpiece na quenching okpomọkụ, na mgbe ahụ, tinye ya na a na-ekpo ọkụ nnu bath nke na-eme ka a ụfọdụ Ọdịdị na-agbanwe maka oge iji nweta bainite na ndị ọzọ owuwu, nke mere na o nwere elu ike na ike. The quenching nchegbu dị ntakịrị, nke nwere ike igbochi denaturation na cracking. Kwesịrị ekwesị maka akụkụ dị mkpa ma buru ibu.
