I-Chromium Carbide Powder yoMboneleli ococekileyo oPhezulu
Ingcaciso yeMveliso
I-Chromium carbide metal chromium (i-chromium trioxide) kunye nekhabhoni zifakwe kwi-vacuum.I-formula yayo ye-molecular yi-Cr3C2 (ipesenti ye-theoretical weight of carbon yi-13%), ubuninzi be-6.2g / cm3 kwaye ubunzima bungaphezu kwe-HV2200.Ukubonakala kwe-chromium carbide powder yisilivere engwevu.I-Chromium carbide powder yindawo ephezulu yokunyibilika kwezinto ezingaphiliyo ezinokumelana nokunxiba kakuhle, ukumelana nokugqwala kunye nokumelana ne-oxidation kwindawo yobushushu obuphezulu (i-1000-1100 degrees).

Isicelo esingundoqo
I-lattice ye-chromium carbide ilungile kwaye imbi, inendawo yokunyibilika ye-1895 ° C. Ngenxa yeempawu zayo ezibalaseleyo zokumelana nokunxiba okuphezulu, ukumelana nokugqwala kunye nokumelana nobushushu obuphezulu, isetyenziswa ikakhulu kwi:
● Ukwenziwa kwezixhobo ezikhethekileyo ze-welding, ii-electrodes ze-surfacing series, i-flux-coreed wires.
● I-carbide ene-cemented, eyongeza i-Cr3C2 ekuveliseni i-carbide ene-cemented ayikwazi ukucokisa kuphela i-WC, kodwa iphinde iphucule amandla kunye nobunzima be-alloy, kwaye inokuphucula kakhulu ukuxhatshazwa kwe-corrosion ye-alloy.
● Isixhobo sokutshiza se-Thermal somgubo, esekwe kwi-Cr3C2 kunye nokongeza i-Nicr superalloy kwi-alloy powder esetyenzisiweyo, usebenzisa i-plasma yokutshiza, inokuvelisa i-high wear-resistant, i-corrosion-resistant, i-high-temperature resistant coatings, esetyenziswa ngokubanzi kwii-fan blades, izitywina zaphukile, I-boiler "iityhubhu ezine", njl.
● I-arc yokutshiza ucingo kunye ne-arc edibeneyo yocingo lwe-tubular, i-arc yokutshiza intambo yongezwa kunye nezinto ze-Cr3C2, eziphucula ukuxhathisa ukushisa okuphezulu kunye nokumelana nokunxiba.Isetyenziselwa ukulungiswa kunye nokugcinwa kokukhusela "iibhobho ezine" zebhoyila, kunye nokuxhatshazwa kwe-iron-making groove kwi-metallurgical industry.Ipleyiti ye-Lining, isityalo samandla sokugaya isilivere, ngenxa yokusetyenziswa kwe-Cr3C2 yongezelela ukhuseleko lwe-welding wire surfacing, iphucula kakhulu ubomi benkonzo.
