Iyo yekupfeka-inodzivirira layer yealloy inonyanya chromium alloy, uye zvimwe zvikamu zvealloy senge manganese, molybdenum, niobium uye nickel inowedzerwawo.Iyo carbides mumetallographic chimiro ndeye fibrous kugovera, uye iyo fiber kutungamira iri perpendicular kumusoro.Iyo micro hardness ye carbide inogona kusvika pamusoro pehv1700-2000, uye kuoma kwepamusoro kunogona kusvika HRC58-62.Alloy carbides ane kugadzikana kwakasimba pakupisa kwepamusoro, anochengetedza kuomarara kwakanyanya, uye ane yakanaka oxidation kuramba.Vanogona kushandiswa kazhinji pasi pe500 ℃.
Iyo yekupfeka-inodzivirira layer ine mitsetse yakamanikana (2.5-3.5mm), migero yakafara (8-12mm), macurves (s, w), nezvimwe;Iyo inonyanya kuumbwa nechromium alloy, uye zvimwe zvikamu zvealloy senge manganese, molybdenum, niobium, nickel uye boron inowedzerwawo.Iyo carbides mune metallographic chimiro inogoverwa mune fibrous fomu, uye iyo fiber kutungamira iri perpendicular kumusoro.The carbide content is 40-60%, microhardness inogona kusvika pamusoro pehv1700, uye kuoma kwepamusoro kunogona kusvika HRC58-62.
