Xa kuthelekiswa neenkqubo ezifana nokucwenga kunyeunyango olungaphezulu, ukucoca kubonakala kuyinyathelo elingabalulekanga.Uninzi lwenu alunakucingela ukucoca utyalo-mali olunexabiso, kuba ukucoca kubiza ixesha nemali kuphela.Kodwa eneneni, ukucoca kubalulekile kumgangatho wemveliso kwaye kunempembelelo enkulu kwinkqubo elandelayo.Kuyimfuneko ukuhlalutya izizathu zokuba kutheni ukucoca kubaluleke kakhulu.
Ngaphambi kokunyanga kobushushu, umphezulu we-workpiece ngokuqhelekileyo ubonakala ucocekile kwaye awunaziphene ekuhloleni okubonakalayo.Nangona kunjalo, kwiinkqubo emva kokunyangwa kobushushu (njenge-nitriding), iingxaki ezibangelwa ukucoceka komgangatho ophantsi zivezwa.Ukuphinda kusetyenzwe ngokutsha kweemveliso ezinoziphene kubiza imali eninzi ngokwexesha nemali, kwaye iimveliso ezineziphene azinakuphinda zisetyenzwe kwiimeko ezininzi.
Ukuba kukho enye yeengxaki ezinjalo, kufuneka siphande oonobangela ngokukhawuleza.Izizathu zoomatshini kunye nezixhobo kufuneka zihlolwe kuqala: uhlobo lwezinto eziphathekayo, imilo yamacandelo, inkqubo ye-nitriding furnace, kunye nokulungiswa koomatshini.Ukuba ezi zinto zinokukhutshelwa ngaphandle, i-defect idla ngokubangelwa yi-diffusion-blocking layer engabonakaliyo kumphezulu we-workpiece, nto leyo ethetha ukuba yintsalela kwindawo ecocekileyo ebonakalayo ebangela isiphene.
Ngaphambi kokunyanga kobushushu, inxalenye idlula kwiinkqubo ezininzi, okubangelwa ukuguqulwa kwendawo.Zimbini iindidi eziphambili zotshintsho.
Utshintsho kumatshini: ukuguqulwa;i-extrusionukusila.
Utshintsho lwekhemikhali: iileya zephosphate (umz. i-zinc phosphating ukuncedisa ekuzobeni);iikhompawundi zokunqanda ukubola;i-chlorine, i-phosphorus okanye i-sulfure inokuthi ifakwe kwi-lubricant yokupholisa, i-saponification fluid, i-oyile kunye nezinye izongezo;i-reagent yokubona ukuqhekeka komphezulu.
Indlela yokucoca i-workpiece ukuqinisekisa ukucoceka kwendawo?
Ngokuqhelekileyo i-95-99% yamanzi kunye ne-agent ye-1-5% yokucoca isetyenziselwa ukucoca i-workpiece, kwaye umgangatho wamanzi ubaluleke kakhulu.Ukungcola emanzini okufana ne-calcium, i-magnesium, i-sodium, i-potassium, kunye ne-chloride inokuhlala phezu kwendawo yokusebenza emva kokumisa ukwenza umqobo wokusasaza, ngoko ke amanzi adibeneyo kunye ne-conductivity ukuya kwi-50 µS / cm kufuneka asetyenziswe ukukhusela. iingxaki ngexesha lokucoca.
Inkqubo yokucoca ngamanzi iqulethe iindidi ezimbini zamacandelo: i-agent eyintloko yokucoca kunye ne-agent esebenzayo.
I-agent eyintloko yokucoca: Iqulethe izinto ezingabonakaliyo okanye eziphilayo, ezifana ne-alkali, i-phosphate, i-silicate, kunye ne-amine.Iyakwazi ukulungelelanisa i-pH, ibonelele nge-conductivity yombane, kunye ne-saponify igrisi.
I-agent esebenzayo ebusweni: Iqulethe izinto eziphilayo, ezifana ne-alkyl benzene sulfonates kunye ne-fatty alcohol ethoxylates, kwaye idlala indima yokunyibilikisa kunye nokusasaza i-oyile kunye namafutha.
Iiparamitha ezine ezibalulekileyo zokucoca ngamanzi kukucoca ulwelo, ixesha lokucoca, ubushushu bokucoca kunye nendlela yokucoca.
1. Ukucoca ulwelo
Umbane wokucoca kufuneka ulungelelanise inxalenye (uhlobo lwezinto eziphathekayo), ukungcola kwangoku kunye nokulandelayounyango olungaphezulu.
2. Ixesha lokucoca
Ixesha lokucoca lixhomekeke kuhlobo kunye nobungakanani bokungcola kwaye kunokuxhomekeka kulandelelwano olunikiweyo lomgca wokucoca ukuze ungaphazamisi amanyathelo omsebenzi olandelayo.
3. Ukucoca ubushushu
Ukushisa okuphezulu kokucoca kuya kunciphisa i-viscosity yeoli kwaye kunyibilike igrisi, okwenza kube lula kwaye kulula ukususa ezi zinto.
4. Indlela yokucoca
Imisebenzi eyahlukeneyo yaziswa ngezixhobo zokucoca, ezinje: ukujikeleza kwetanki, ukuphuphuma, ukutshiza, kunye ne-ultrasonic.Indlela yokucoca ixhomekeke kuhlobo kunye nokuma kwenxalenye, ukungcola kunye nexesha elikhoyo lokucoca.
Ezi parameters zine kufuneka zilungelelaniswe kwimeko kanye.Ukunikezelwa kwamandla amaninzi (umatshini, i-thermal okanye ikhemikhali) okanye ixesha elide lonyango liya kuphucula umphumo wokucoca.Ukongezelela, ukuhamba okunamandla kwamanzi okucoca kuya kuphucula umphumo wokucoca kumaqondo aphantsi.
Kuyafaneleka ukuba uqaphele ukuba ezinye zezinto ezingcolileyo zixhomekeke ngokugqithisileyo kwaye azikwazi ukususwa ngokucoca.Ungcoliseko olunjalo lunokususwa kuphela ngeenkqubo ezifana nokusila, ukuqhunyiswa kwesanti, kunye ne-pre-oxidation.
