Izinto kunye neePropati:
Umngundo we-alloy oqinileyo usekwe kwi-tungsten-cobalt (WC{1}}Co) ingxubevange, kunye nomxholo we-cobalt olungelelaniswe kuluhlu lwe-6%-25% ngokuxhomekeke kwimeko yesicelo. Izinto eziphathekayo zine-microhardness ye-HRA89-93, amandla okuguquguquka kwe-3000-4000MPa, kunye ne-coefficient yokwandisa i-thermal (4.5-6.5) × 10 ^ -6 / idigri, ukuqinisekisa ukuzinza kwesakhiwo kwiqondo lokushisa ukuya kwi-800 degree. Ukumelana kwayo nokunxiba kumaxesha angama-20-30 aphezulu kuneyentsimbi yesixhobo, okwenza kube yinto efanelekileyo kwizicelo zoxinzelelo oluphezulu.
Inkqubo yeMveliso:
Inkqubo yokuvelisa engundoqo ibandakanya
Ukulungiselela i-Powder Metallurgy: I-tungsten carbide kunye ne-cobalt powder ixutywe kwaye icinezelwe, emva koko i-sintered phantsi kwe-vacuum kwi-1360-1500℃ukwenza i-alloy dense.
UkuSila Ngokuchanekileyo: Ivili lokusila idayimani lisetyenziselwa i-nanometer{0}}ukusetyenzwa komphezulu womgangatho, ukufumana uburhabaxa be-Ra0.02μm.
UNyango loBubushushu lokomeleza:{0}uxinzelelo lwe-nitriding ephantsi lusetyenziswa ukonyusa ubulukhuni bomphezulu ukuya ngaphezulu kwe-HV1800.
Ukuphuculwa koLwakhiwo: Itekhnoloji yoyilo lweGradient isetyenziselwe ukuqinisekisa ukuba umxholo we-cobalt kwindawo yomgangatho we-mold ungaphantsi kunengaphakathi, ukulinganisa ukuxhathisa kunye nokuqina.
Imimandla yesicelo:
Kwimveliso yemizi-mveliso, isetyenziswa ikakhulu kwezi ndawo zilandelayo
I-Metal Processing: Ukuzoba kunye nokwenza ucingo lwe-φ0.1-20mm, ngokuchaneka kwe-± 0.005mm yokucubungula ucingo.
Ukwenziwa kweZithuthi: Isihloko esibandayo sendawo yokuhlala yevalve ye-injini, kunye neseti enye yokungunda ekwaziyo ukuhlala ngaphezulu kwe-500,000 yemijikelo.
I-Petroleum Extraction: Ukuveliswa kwezixhobo zokuvala{0}}zevalvu yesulfure, ezinokusebenza ngokuzinzileyo kwindawo ene-H2S yoxinaniso ye-15%.
Umzi-mveliso wezobuNxibelelalwazi: Ukugximfizwa ngokuchanekileyo kweefreyimu zelothe, kunye nokukhutshwa okungenanto okuyi-0.003mm
