Synergistic methods for the production of high-strength …

Boron carbide (B4C) is a non-oxide ceramic in the same class of nonmetallic hard materials as silicon carbide and diamond. The high hardness, high elastic modulus and low density of B4C make it a nearly ideal material for personnel and vehicular armor. B4C plates formed via hot-pressing are currently issued to U.S. soldiers and have exhibited excellent performance; however, hot-pressed

Silicon carbide, SIC, is one of the hardest materials …

Silicon carbide, SIC, is one of the hardest materials known. Surpassed in hardness only by diamond, it is sometimes known commercially as carborundum. Silicon carbide is used primarily as an abrasive for sandpaper and is manufactured by heating common sand (silicon dioxide, SiO 2 …

A dash of silicon improves boron carbide body armor - …

Boron carbide, dubbed “black diamond,” is a human-made material, which ranks second below another synthetic material called cubic boron nitride for hardness.

Silicon Carbide SiC Material Properties - Accuratus

Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.

Effect of process parameters and niobium carbide …

When niobium carbide addition is 9 %, the hardness of the cladding layer is 435 HV 0.2, which is 72.5 % of niobium carbide‐free Ni60 A coating. (3) With the increase of niobium carbide addition in the cladding layer, the wear loss of the sample decreases first and then increases.
