Umcu we-tungsten we-carbide wenziwa ikakhulu nge-WC tungsten carbide kunye ne-Cobalt powder exutywe yindlela ye-metallurgical nge-pulverization, ukugaya ibhola, ukucinezela kunye ne-sintering, amacandelo aphambili e-alloy yi-WC kunye ne-Co, umxholo we-WC kunye ne-Co kwiindlela ezahlukeneyo zokusetyenziswa kwe-tungsten carbide strip. ayifani, kwaye uluhlu losetyenziso lubanzi kakhulu.
Enye yezona zinto zininzi ze-tungsten carbide strips, ithiywe ngenxa yesimo sayo soxande samacwecwe (okanye izikwere), ezaziwa ngokuba yi-tungsten carbide strip/plates. Umtya we-tungsten carbide unobulukhuni obubalaseleyo, ukumelana nokunxiba kakuhle, imodyuli ephezulu enwebekayo, amandla acinezelayo aphezulu, uzinzo oluhle lweekhemikhali (iasidi, ialkali, ukumelana nobushushu obuphezulu be-oxidation), ukuqina kwempembelelo ephantsi, ukwandiswa kwe-coefficient ephantsi, i-thermal kunye ne-conductivity yombane efana nentsimbi kunye nayo. ialloyi.
Ziziphi izizathu zedesolderingyemicu yetungsten carbide? I-Chuangrui carbide iya kuphendula ngokulandelayo:
(1) Umphezulu wokubhobhoza we-tungsten carbide awugatywanga okanye ukhazimliswe phambi kwe-weld, kwaye umaleko we-oksidi kumphezulu wokubhobhoza unciphisa umphumo wokumanzisa kwesinyithi sokuqhafaza kwaye buthathaka amandla okudibanisa i-weld.
(2)Ukuchithwaiya kwenzeka kwakhona xa i-agent ekhangayo ingakhethwanga kwaye isetyenziswe ngokungafanelekanga, umzekelo, xa i-borax isetyenziswe njenge-agent agent, i-borax ayikwazi ukudlala ngokufanelekileyo indima ye-deoxidizing ngenxa yokuba i-borax iqulethe umswakama obuninzi, kwaye izinto zokubhobhoza azikwazi ukumanziswa kakuhle. phezu kobuso bobhedu, kunye nedesolderinginto eyenzekayo.
(3) Ubushushu obuchanekileyo bokubrawuza kufuneka bube yi-30 ~ 50 °C ngaphezu kwendawo yokunyibilikisa yesinyithi sokunyibilikisa, kwayedesolderingiyakwenzeka ukuba iqondo lobushushu liphezulu kakhulu okanye lisezantsi kakhulu. Ukutshisa kakhulu kunokubangela i-oxidation kwi-weld. Ukusebenzisa i-zinc-containing metal brazing kuya kunika i-weld umbala ohlaza okwesibhakabhaka okanye omhlophe. Xa ubushushu bokushisa buphantsi kakhulu, i-weld eyomileyo iya kwenziwa, kwaye i-weld yangaphakathi iya kugqunywa nge-porosity kunye ne-slag inclusions. Le miqathango mibini ingentla iya kunciphisa amandla e-weld, kwaye kulula ukuyidibanisa xa ilola okanye isetyenziswe.
(4)Kwinkqubo yokuqhafaza, akukho kukhutshwa kwe-slag ngexesha elifanelekileyo okanye ukukhutshwa kwe-slag eyaneleyo, ukwenzela ukuba inani elikhulu le-agent ye-brazing slag lihlale kwi-weld, elinciphisa amandla e-weld kwaye libangele.desoldering.
