| Abstract Scope |
The aim of the study is to strengthen the working surfaces of parts operated in aggressive conditions on equipment for vulcanizing products made of new elastomeric materials based on a copolymer of vinyl di-fluoride and hexopropylene, ethylene-propylene rubber. The coatings were applied in the CBC process. Gaseous products interact with the elements of the powder system (Al, Si, B, Cr) and convert them to the gas phase (SiI3, AlCl, AlCl2, AlCl3, BF3, CrF, CrF2, , AlI). The microhardness of the chromium layers is 20000-22000 MPa, which is due to the presence of the FeB phase. The results obtained indicate that silicon alloys only the Fe2B phase. The obtained results indicate that silicon is displaced from the boride zone to the α-phase sublayer, alloying only the Fe2B phase. |
