1. Ingqikelelo yokwaleka komphezulu wedayimani
Ukwaleka komphezulu wedayimani, kubhekisa kusetyenziso lwetekhnoloji yonyango lomphezulu kumphezulu wedayimani oqatywe ngomaleko wezinye izinto zefilimu. Njengezinto zokugquma, ngokuqhelekileyo isinyithi (kubandakanya i-alloy), njengobhedu, i-nickel, i-titanium, i-molybdenum, i-copper tin titanium alloy, i-nickel cobalt alloy, i-nickel cobalt phosphorus alloy, njl.; izinto zokugquma nazo ezinye izinto ezingezizo ezentsimbi, ezifana neeseramikhi, i-titanium carbide, i-titanium ammonia kunye nezinye iikhompawundi zemathiriyeli eqinile enqabileyo. Xa izinto zokugquma ziyintsimbi, zinokubizwa ngokuba yi-diamond surface metalation.
Injongo yokwaleka komphezulu kukunika amasuntswana edayimani ngeempawu ezikhethekileyo zomzimba kunye neekhemikhali, ukuze kuphuculwe ukusebenza kwazo. Ngokomzekelo, ukusetyenziswa kwevili lokusila le-diamond abrasive-coated diamond abrasive resin, ubomi bayo benkonzo bandiswa kakhulu.
2. Ukuhlelwa kwendlela yokwaleka komhlaba
I-Industrial surface treatment method method jonga lo mzobo ungezantsi, oye wasetyenziswa ngokwenene kwindlela yokugquma umphezulu onzima kakhulu, ethandwa kakhulu kukucholwa kweekhemikhali ezimanzi (akukho plating ye-electrolysis) kunye ne-plating, i-plating eyomileyo (ekwaziwa ngokuba yi-vacuum plating) kwi-chemical deposition deposition (CVD) kunye nokubeka umphunga womzimba (PVD), kubandakanywa ne-vacuum ye-vacuum powder kwi-method ye-sinterlug.
3. Ubukhulu bePlating bumele indlela
Ngenxa yokuba ubunzima bokugquma ubuso be-diamond abrasive particles kunzima ukucacisa ngokuthe ngqo, ngokuqhelekileyo kubonakaliswa njengenzuzo yobunzima (%). Kukho iindlela ezimbini zokubonisa ukunyuswa kobunzima:
Apho A kukufumana ubunzima (%); I-G1 bubunzima bokugaya ngaphambi kokutyalwa; I-G2 bubunzima bokugquma; U-G bubunzima bubonke (G=G1 + G2)
4. Umphumo wedayimani umphezulu ukutyabeka phezu diamond ukusebenza isixhobo
Kwisixhobo sedayimane esenziwe nge-Fe, Cu, Co kunye ne-Ni, amasuntswana edayimani anokufakwa ngoomatshini kuphela kwi-agent ye-agent matrix ngenxa yokungabikho kwekhemikhali edibeneyo ye-arhente ebophelelayo engentla kunye nokungabikho kokungena kwi-interface. Ngaphantsi kwesenzo samandla okugaya, xa idayimane yokugaya idayimane ibonakaliswe kwicandelo eliphezulu, isinyithi somzimba wesondo siya kulahlekelwa ngamaqhekeza edayimani kwaye siwe ngokwawo, okunciphisa ubomi benkonzo kunye nokusebenza kakuhle kwezixhobo zedayimani, kunye nomphumo wokugaya idayimani awukwazi ukudlala ngokupheleleyo. Ngoko ke, i-diamond surface ineempawu ze-metallization, ezinokuphucula ngokufanelekileyo ubomi benkonzo kunye nokusebenza kakuhle kwezixhobo zedayimani. Undoqo wayo kukwenza izinto ezibophelelayo ezifana ne-Ti okanye i-alloy yayo egqunywe ngokuthe ngqo kumphezulu wedayimani, ngokufudumeza kunye nokufudumeza unyango, ukwenzela ukuba umphezulu wedayimani wenze umaleko wokudibanisa imichiza efanayo.
Ngokugquma amasuntswana edayimani yokusila, ukusabela yokwaleka kunye nedayimani metalize umphezulu diamond. Kwelinye icala, umphezulu wedayimani owenziwe ngesinyithi kunye ne-arhente yokubopha umzimba wesinyithi phakathi kwendibaniselwano yesinyithi, ke ngoko, unyango lwedayimani yoxinzelelo olubandayo lolwelo lwe-sintering kunye nokutshisa okuqinileyo kwesigaba sinokusebenza okubanzi, ngoko ke i-alloy yomzimba wokudityaniswa kwedayimani yokusila ukuqinisa ingqolowa yanda, ukunciphisa isixhobo sedayimani ekusetyenzisweni kokusila, ukuphucula ubomi benkonzo kunye nokusebenza kakuhle kwezixhobo zedayimani.
5. Yiyiphi imisebenzi ephambili yonyango lwedayimane yokwaleka?
1. Phucula isakhono sokufakela somzimba wosana olungekazalwa ukuze ufake idayimani.
Ngenxa yokwanda kwe-thermal kunye nokucutheka okubandayo, uxinzelelo olukhulu lobushushu lwenziwa kwindawo yoqhagamshelwano phakathi kwedayimani kunye nomzimba wetayara, nto leyo eya kwenza idayimani kunye nebhanti loqhagamshelwano lomzimba wosana luvelise imigca emincinci, ngaloo ndlela kuncitshiswe amandla omzimba wetayara oqatywe ngedayimani. Ukugquma komphezulu wedayimani kunokuphucula iimpawu zedayimani kunye neekhemikhali zedayimani kunye nojongano lomzimba, ngohlalutyo lwe-spectrum yamandla, iqinisekisile ukuba i-carbide yesinyithi kwifilimu ukusuka ngaphakathi ukuya ngaphandle ngokuthe ngcembe iguqukela kwizinto zetsimbi, ezibizwa ngokuba yifilimu ye-MeC-Me, umphezulu wedayimane kunye nefilimu yibhondi yeekhemikhali, le ndibaniselwano kuphela inokuphucula isakhono sedayimani, okanye siphucule isakhono somzimba wedayimani. Oko kukuthi, ukugquma kusebenza njengebhulorho ebophelelayo phakathi kwezi zibini.
2. Ukuphucula amandla edayimani.
Ngenxa yokuba iikristale zedayimane zihlala zineziphene zangaphakathi, ezifana ne-microcracks, i-cavities encinci, njl., ezi ziphene zangaphakathi kwiikristali zihlawulwa ngokuzalisa i-membrane ye-MeC-Me. Ukucwenga kudlala indima yokuqinisa kunye nokuqina. Ukufakwa kweekhemikhali kunye ne-plating kunokuphucula amandla eemveliso eziphantsi, eziphakathi kunye neziphezulu.
3. Cothisa ukothuka kobushushu.
Utyatyazo lwesinyithi lucotha kunolo lwedayimani abrasive. Ubushushu bokugaya bugqithiselwa kwi-agent ebophelelayo ye-resin ekudibaneni ne-particle yokusila, ukwenzela ukuba itshiswe ngaphandle kwempembelelo yeqondo lokushisa eliphezulu ngokukhawuleza, ukuze kugcinwe amandla ayo okubamba kwi-diamond abrasive.
4. Ukwahluka kunye nesiphumo sokukhusela.
Ngexesha lobushushu obuphezulu be-sintering kunye nokugaya kwiqondo lokushisa eliphezulu, i-coating layer iyahlula kwaye ikhusele idayimane ukukhusela i-graphitization, i-oxidation okanye ezinye iinguqu zeekhemikhali.
