Iingxaki eziqhelekileyo kunye noCause Cause Analysis of Hard Alloy Pressing
I-Hard alloy yimathiriyeli ye-alloy eyenziwe kwiikhompawundi eziqinileyo zesinyithi esichasayo kunye nesinyithi esidityanisiweyo ngenkqubo ye-metallurgy engumgubo, enobunzima obuphezulu, ukuxhathisa ukunxiba, ukomelela okulungileyo kunye nokuqina. Ngenxa yokusebenza kwayo okuyingqayizivele, isoloko isetyenziselwa ukwenza izixhobo zokugaya amatye, izixhobo zemigodi, izixhobo zokugaya, izixhobo zokulinganisa, njalo njalo. Isetyenziswa kakhulu kwimimandla efana neoyile negesi, ishishini lemichiza, oomatshini bobunjineli, kunye nolawulo lwamanzi. I-Hard alloy yimathiriyeli eyenziwe ngokucinezela ngenkqubo yesinyithi somgubo.
1. Umaleko
Uninzi lwamaleko luqala ukusuka kwincam kwaye ludlulele kwibillet. Isizathu sokubekwa kwebhloko yoxinzelelo luxinzelelo lwangaphakathi olunwebekayo okanye i-elastic tension kwibhloko yoxinzelelo. Ngokomzekelo, umxholo we-cobalt womxube uphantsi, ubunzima be-carbide buphezulu, i-powder okanye i-particles i-finer, i-agent eyenza i-agent incinci kakhulu okanye isasazwa ngokungalingani, umxube umanzi kakhulu okanye womile kakhulu, uxinzelelo olucinezelayo luninzi kakhulu. inkulu, ubunzima obunye bukhulu kakhulu, imilo yebhloko yokucinezela inzima, ukuguda komngundo kubi kakhulu, kwaye umphezulu wetafile awulingani, konke oku kunokubangela ukwaleka.
2. Iintanda
Isenzeko sokuqhekeka kwendawo engaqhelekanga kwibhloko ecinezelweyo kuthiwa yi-cracking. Ngenxa yoxinzelelo lwe-tensile ngaphakathi kwebhloko yokucinezela ukuba mkhulu kunamandla obunzima bebhloko yoxinzelelo. Uxinzelelo lwe-tensile ngaphakathi kwebhloko yoxinzelelo luvela kuxinzelelo lwangaphakathi olunwebekayo. Izinto ezichaphazela i-delamination nazo zichaphazela iintanda. La manyathelo alandelayo angathathwa ukuze kuncitshiswe ukwenzeka kweentanda: ukwandisa ixesha lokubamba okanye ukuxinzezeleka okuphindaphindiweyo, ukunciphisa uxinzelelo, ubunzima obunye, ukuphucula ukubunjwa kwesikhunta kunye nokwandisa ngokufanelekileyo ukubunjwa kwesikhunta, ukukhawuleza kwesantya sokubunjwa, ukwandisa i-agents, kunye nokwandisa ubuninzi bezinto eziphathekayo.
