Kuongorora kwesimba kwe high-performance chromium corundum zvidhinha

Iyo tembiricha yekamuri yekumanikidza simba repamusoro-kuchena corundum zvidhinha kazhinji 70-100MPa, uye tembiricha yekamuri yekumanikidza simba re high-performance chromium corundum zvidhinha kazhinji > 150MPa, uye simba rayo rakakwirira zvakanyanya kudarika rezvidhinha zvecorundum. Izvi zvinokonzerwa nekuumbwa kweAl2O3-Cr2O3 mhinduro yakasimba pakati pezvimedu uye zvidimbu, pakati pezvimedu uye poda yakatsetseka, uye pakati pehupfu hwakatsetseka uye hupfu hwakatsetseka panguva yekupisa kwechigadzirwa. Mushonga wakasimba unobatanidza zvimedu uye hupfu hwakatsetseka sebhiriji. Pamwe chete, kusimba kwechinyorwa kunovandudzwa zvikuru.
