efere ígwè na-eguzogide iyi

Efere nchara na-eguzogide iyi nwere efere ígwè dị obere carbon na oyi akwa na-eguzogide alloy, yana oyi akwa na-eguzogide alloy na-agụnye 1/3 ruo 1/2 nke mkpokọta ọkpụrụkpụ. N'oge ọrụ, isi ihe na-enye keukwu Njirimara dị ka ike, ike, na ductility iguzogide mpụga ike, mgbe alloy wear-eguzogide oyi akwa na-enye eyi nguzogide ahaziri kpọmkwem ọrụ ọnọdụ.

Oyi akwa na-eguzogide alloy na ihe ndị dị n'okpuru bụ ihe ejikọtara na metallurgically. N'iji akụrụngwa pụrụ iche yana usoro ịgbado ọkụ akpaaka, waya alloy siri ike dị elu, nke na-echebe onwe ya ka a na-ejikọta ya n'otu n'otu na ihe ala. Ngwunye ihe mejupụtara nwere ike ịbụ otu, abụọ, ma ọ bụ ọbụna ọtụtụ ọkwa. N'ihi oke nhịahụ alloy dị iche iche, mgbawa na-agbanwe agbanwe na-etolite n'oge usoro lamination, akara nke efere nchara na-agaghị eyi.

Ihe mejupụtara alloy wear-eguzogide bụ nke chromium alloy, yana ihe ndị ọzọ na-eme ka ihe dị ka manganese, molybdenum, niobium, na nickel gbakwunyere. The carbides na metallographic Ọdịdị bụ fibrous, na eriri gbakwasara perpendicular n'elu. Microhardness carbide nwere ike iru HV 1700-2000, na ike elu nwere ike iru HRC 58-62. Alloy carbides kwụsiri ike na oke okpomọkụ, na-ejigide ike siri ike na nguzogide oxidation dị mma, na-enye ohere ịrụ ọrụ zuru oke n'ime okpomọkụ ruo 500 Celsius.

Okpokoro na-eguzogide iyi nwere ike ịpụta n'ụdị dị warara (2.5-3.5mm) ma ọ bụ obosara (8-12mm), yana usoro agbagọ (S na W). Ihe mejupụtara alloy chromium bụ isi, ihe ndị a nwekwara manganese, molybdenum, niobium, nickel, na boron. A na-ekesa carbides n'ụdị fibrous na nhazi metallographic, na eriri ndị na-agba ọsọ na-adabere na elu. Site na ọdịnaya carbide nke 40-60%, microhardness nwere ike iru HV1700, isi ike elu nwere ike iru HRC58-62. A na-ekewa efere ígwè na-eguzogide iyi n'ime ụzọ atọ: ebumnuche izugbe, mmetụta na-eguzogide ọgwụ na oke okpomọkụ. Ngụkọta ọkpụrụkpụ nke efere ígwè na-eguzogide iyi nwere ike ịdị obere ka 5.5 (2.5+3) mm na oke ka 30 (15+15) mm. Enwere ike ịtụgharị efere ígwè na-adịghị eyi uwe n'ime ọkpọkọ na-adịghị eyi nke nwere dayameta opekempe nke DN200, a pụkwara ịhazi ya ka ọ bụrụ nku aka na-adịghị eyi, tees na-eguzogide ọgwụ na ndị na-ebelata eyi.
