Kedu otu esi eme nyocha metallographic mgbe emenyụchara ọkụ ọkụ induction induction?
Metallographic nnyocha nke pearlite ductile ígwè akụkụ mgbe induction kpo oku quenching ga-eme dị ka JB/T 9205-2008 “Induction kpo oku ọkụ quenching metallographic nnyocha nke pearlite ductile ígwè akụkụ”
1) Mgbe emenyụchara ihe nkedo pearlitic ductile iron n’ọkụ ọkụ ọkụ na-ekpo ọkụ dị elu na nke etiti na obere okpomọkụ (W200T), a ga-ewere ihe nlele metallographic n’etiti mpaghara induction quenching ma ọ bụ n’ebe akọwapụtara site na teknụzụ. ọnọdụ.
2) Mgbe emechara, a na-etinye ihe nlele metallographic na ngwọta mmanya nwere 2% ruo 5% nitric acid site na olu ruo mgbe egosipụtara oyi akwa siri ike.
3) Dịka ntuziaka nhazi microstructure nke egosiri na Tebụl 6.2 na eserese nhazi microstructure na JB/T 9205-2008, mee nyocha metallographic. N’ime ha, akara ule 3 ruo 6 tozuru oke; mgbe enwere ihe ndị pụrụ iche chọrọ, a ga-emejuputa ha dịka akwụkwọ nkà na ụzụ dị mkpa si dị.
Tebụl 6-2 Nkọwa nke nhazi ọkwa microstructure nke nkedo ígwè pearlite ductile ka emenyụchara n’ime ọkụ ọkụ induction.
