Yintoni injongo yonyango lobushushu bomhlaba

①Phucula ukuxhathisa kokunxiba kwamalungu. Umaleko we-high-carbon martensitic hardened surface ungafumaneka ngokungcwatywa kunye nokucima iindawo zentsimbi; i-dispersion hardened surface layer of alloy nitride inokufumaneka ngendlela ye-nitriding yeendawo zentsimbi yealloyi. Ubunzima bomphezulu weendawo zentsimbi ezifunyenwe ngezi ndlela zimbini zinokufikelela kwi-HRC58～62 kunye ne-HV800～1200 ngokulandelanayo. Enye indlela kukwenza ifilimu yokunciphisa kunye ne-anti-adhesive ebusweni bentsimbi ukuphucula iimeko zokubetha, ezinokuthi ziphucule ukuchasana nokugqoka. Ngokomzekelo, indawo yokucoca umphunga ivelisa ifilimu ye-ferroferric oxide enefuthe lokuchasana nokunamathela; i-surface vulcanization ifumana ifilimu ye-sulfide ene-ferrous, enokuba nayo zombini i-anti-wear and anti-adhesion effects. Inkqubo ye-multi-element co-infiltration ephuhliswe kwiminyaka yamuva nje, efana ne-oxygen-nitriding, i-sulfur-nitrogen co-infiltration, i-carbon-nitrogen-sulfur-oxy-boron i-five-element co-infiltration, njl. -i-hardness diffusion layer kunye ne-anti-sticking okanye i-anti-friction film, iphucula ngokufanelekileyo Ukuxhatshazwa kokugqoka kwamacandelo, ngokukodwa ukuxhathisa ukunamathela.

②Phucula ukudinwa kwamalungu. Iindlela ze-Carburizing, i-nitriding, i-nitriding ethambileyo kunye ne-carbonitriding zonke zinokwenza umphezulu weendawo zentsimbi zomeleze ngelixa zenza uxinzelelo olushiyekileyo kumphezulu wamalungu, ngokufanelekileyo ukuphucula amandla okudinwa kwamalungu.

③Phucula ukuxhathisa umhlwa kunye nokumelana nobushushu obuphezulu be-oxidation yamalungu. Ngokomzekelo, i-nitriding inokuphucula ukuxhathisa kwe-atmospheric corrosion of parts; emva kwe-aluminizing, i-chromizing, kunye ne-siliconizing iinxalenye zetsimbi, iya kusabela nge-oksijini okanye i-media corrosive ukuze yenze i-Al2O3 exineneyo kwaye izinzile, i-SiO2 ifilimu yokukhusela, iphucula ukuxhathisa kwe-corrosion kunye nokushisa okuphezulu kwe-oxidation.

Ngokuqhelekileyo, iindawo zentsimbi ziya kuba yi-embrittlement xa ziqinisiwe. Xa indlela yokuqina komphezulu isetyenziselwa ukunyusa ukuqina komphezulu, ingundoqo isenokuthi igcinwe kwimeko yokuqina okulungileyo, ngoko inokusombulula ngcono ukuphikisana phakathi kokuqina kweengxenye zentsimbi kunye nokuqina kwayo kunendlela edibeneyo yokucima ukuqina kweengxenye. Unyango lobushushu beMichiza lutshintsha ukwakheka kweekhemikhali kunye nesakhiwo somphezulu wamalungu entsimbi ngaxeshanye, ngoko ke lusebenza ngakumbi kuneendlela zokuqina komphezulu ezifana nokufakwa kombane ngamaza ombane aphezulu naphakathi kunye nokucinywa komlilo. Ukuba into yokungena ikhethwe ngokufanelekileyo, umaleko womphezulu ofanelekileyo kwiimfuno ezahlukeneyo zokusebenza zecandelo unokufumaneka.
