Akụkụ bụ isi nke mmiri ozuzo na-eme ka igwe anaghị agba nchara sie ike:
Ike dị elu na nguzogide corrosion: Mmiri ozuzo na-eme ka igwe anaghị agba nchara na-edobe nguzogide corrosion nke ụdị igwe anaghị agba nchara ma na-enweta ike dị elu site na usoro ọgwụgwọ okpomọkụ.
Usoro ọgwụgwọ okpomọkụ:
1.Solution Heat Ọgwụgwọ: A na-ekpo ọkụ nchara ahụ na okpomọkụ dị elu (na-emekarị ihe dịka 1000 ° C ruo 1100 ° C) iji gbazee ihe ndị na-emepụta ihe (dị ka aluminom, ọla kọpa, ma ọ bụ niobium) n'ime ngwọta siri ike.
2. ịka nká: Mgbe emenyụchara (ngwa ngwa jụrụ oyi), ígwè ahụ na-aka nká na obere okpomọkụ (ihe dịka 500 ° C ruo 700 ° C). Nke a na-akwalite mmiri ozuzo nke ụmụ irighiri ihe na-eme ka ike sie ike na-egbochi mmegharị ahụ, si otú ahụ na-ewusi ihe ahụ ike.
3. Ihe mejupụtara: Igwe anaghị agba nchara siri ike nke mmiri ozuzo na-ejikarị ihe ndị dị ka ọla kọpa, aluminum, niobium, titanium, ma ọ bụ molybdenum, nke na-enye aka na mmiri ozuzo nke usoro siri ike na-eme ka ígwè ahụ dịkwuo ike.
akara ule: Ihe atụ ama ama nke igwe anaghị agba nchara nke mmiri ozuzo siri ike bụ igwe anaghị agba nchara 17-4 PH, nke nwere ígwè, chromium, nickel, na ọla kọpa. Akara akara ndị ọzọ, dị ka 15-5 PH na 13-8 Mo, na-ejikarị na ngwa chọrọ ngwakọta nke ike dị elu na nguzogide corrosion.
Ngwa: A na-eji igwe anaghị agba nchara siri ike mmiri ozuzo na ụlọ ọrụ ebe ma ike dị elu na nguzogide corrosion dị mkpa, dịka na:
