Chromium Carbide Powder High Purity Supplier
Tlhaloso ea Sehlahisoa
Chromium carbide metal chromium (chromium trioxide) le carbon li entsoe ka vacuum.Foromo ea eona ea limolek'hule ke Cr3C2 (tekanyo ea boima ba k'habone ke 13%), letsoalo ke 6.2g/cm3 mme boima bo kaholimo ho HV2200.Ponahalo ea phofo ea chromium carbide ke silevera ea gray.Chromium carbide powder ke sebaka se phahameng sa ho qhibiliha sa inorganic se nang le khanyetso e ntle ea ho apara, ho hanyetsa kutu le ho hanyetsa oxidation sebakeng se phahameng sa mocheso (1000-1100 degrees).

Lattice ea chromium carbide e ntle ebile e mpe, e na le ntlha ea ho qhibiliha ea 1895 ° C. Ka lebaka la litšobotsi tsa eona tse babatsehang tsa ho hanyetsa ho apara, ho hanyetsa kutu le ho hanyetsa mocheso o phahameng, e sebelisoa haholo-holo ho:
● Ho etsoa ha thepa e khethehileng ea ho cheselletsa, li-electrode tse ka holim'a metsi, lithapo tsa flux-cored.
● Carbide e entsoeng ka samente, e eketsang Cr3C2 ha ho etsoa carbide e entsoeng ka samente e ke ke ea ntlafatsa feela lijo-thollo tsa WC, empa hape e ntlafatsa matla le ho thatafala ha motsoako, 'me e ka ntlafatsa haholo ho hanyetsa ha kutu ea alloy.
● Thermal spraying powder material, e thehiloeng ho Cr3C2 le ho eketsa Nicr superalloy ho phofo ea alloy e entsoeng, ka ho sebelisa plasma spraying, e ka hlahisa liphahlo tse phahameng tse sa senyeheng, tse thibelang ho bola, tse nang le mocheso o phahameng, tse sebelisoang haholo ka li-blades tsa fan, litiiso li robehile, Boiler "li-tubes tse 'nè", joalo-joalo.
● Arc sprayed terata le submerged arc welded tubular terata, arc sprayed terata e eketsoa ka Cr3C2 lintho tse bonahalang, e leng ho ntlafatsa phahameng ho hanyetsa mocheso le ho apara ho hanyetsa.E sebelisoa ho lokisoa le ho thibela "liphaephe tse 'nè" tsa boiler, le ho se sebetse ha lesela la lesela le entsoeng ka tšepe lefapheng la metallurgical.Letlapa la lesela, semela sa matla se sila silevera, ka lebaka la ts'ebeliso ea Cr3C2 se ekelitse ts'ireletso ea terata ea tubular, e ntlafatsa bophelo ba ts'ebeletso haholo.
