Preparation and characterization of physically modified

Preparation and characterization of physically modified

Apr 15, 2013 Physical surface modification of glass beads was carried out by friction and impaction in a ball mill (Ball Mill S2, Retsch, Haan/Germany). To get surfaces with different shades of roughness, grinding materials with different Mohs hardness were chosen and glass beads were processed for 8 h and 4 h at 424 rpm.The grinding materials used were tungsten carbide (TC) and quartz (Q) ().

Some carbide material remains as a contaminant in the powder after synthesis, however, and the process produces large particles that must be ground into finer powder in cobalt-bonded tungsten carbide mills. The tungsten carbide and cobalt add more contaminants at grain boundaries of the titanium diboride particles, Logan said.

Brinell hardness testing insight Struers.com

The method proved reliable and in 1900 the Brinell hardness test was officially born. Today, the Brinell test is performed using a Brinell hardness test unit. The machine presses a tungsten carbide ball into the sample, and then optically measures the diameter of the impression. Indenter sizes: 1, 2.5, 5 and 10 mm. Loads: From 1 kgf to 3000 kgf.

Carbides and Carbide Materials hardmetals Selection

Silicon carbide (SiC) is a compound of silicon metalloid and oxygen. Typically, SiC is used in the alpha silicon carbide structural form. Silicon carbide is a black, high-hardness ceramic that is usually harder than alumina. Depending on the addition of impurities SiC may be green or black in color. Fully-dense SiC can be transparent (moissanite).
