To improve the oxidation resistance of the SiC-MoSi2 coating prepared by two-step pack cementation, a liquid Si …. The results show that the size and number of the cracks in the modified coating decreased evidently after infiltrating Si …. The oxidation test results in air at 1773 K show that the mass loss of the SiC-MoSi2 coating coated carbon/carbon (C …

A SiC coating for carbon/carbon (C/C) composites was produced by pack cementation to use as a bonding and buffer layer …-like cell responses of the coating were investigated. The results confirmed that the SiC coating displayed a dense and uniform … microstructure. MG63 cells attached and spread favorably on SiC coating, and cell proliferation was better on SiC coating than on …

In order to protect carbon/carbon (C/C) composites from oxidation at 1700°C, a MoSi2–SiC–Si/MoSi2 coating was prepared … cementation, and the MoSi2 outer layer was prepared by slurry coating using silicon-sol as the caking agent. The microstructures … of the as-prepared coating were examined by X-ray diffraction and scanning electron microscope. Oxidation test shows that …

A novel Mo–Si–B double-layer coating was prepared for the carbon/carbon (C/C) composites by pack cementation in an … argon atmosphere. The structures of the double-layer coatings were characterized by XRD and SEM. The as-received coating … oxidation protective coating was principally due to producing eutectic glass film for decreasing oxygen diffusing through the …

In order to protect carbon/carbon (C/C) composites against oxidation, a (Mo,W)Si2 coating was prepared on the surface … microstructures and oxidation protective ability of the as-received coating were investigated. The results show that the (Mo,W)Si2 … outer layer coating containing free Si has a good bonding with SiC inner layer. The as-prepared SiC/(Mo,W)Si2 coating can …

SiC coating for carbon/carbon composites was prepared by pack cementation method. The effects of coating process on the … the infiltrated Si improved the interfaces bonding during the coating process, the flexural strength and flexural modulus …
