rather than phosphorous in the Ni-P coating should be responsible for the catalytic graphitization[14]. Up to date, we have not seen any report about catalytic graphitization of carbon materials...) and degree of graphitization of carbon materials[15-16]. Fig.1 shows the XRD patterns of carbon fibers without alloy coating at different heat treatment temperatures (HTTs). It can be observed from Fig.1......
Effect of RE on the Brittleness of Electrolytic Boronization Coating余忠荪,邵光杰,郭瑞强摘 要:<正> The electrolytic coatings of boron and RE-boron on medium carbon steel are carried out in molten salt mix-tures respectively.The brittleness of both coatings has been measured by using sound-emission with the methodof three point bending.Results show......
Nano-Composite Superfine Nickel Powder Double Absorbent Coating Designing () 摘要:We adopt a definite procedure to compound traditional absorbing material-superfine powder nickel and nano -SiC... material, but each component of the composite material must have matched electromagnetic parameter with another. For matching double-coating structure, it ought to modulate the correlativity of each......
