Effect of surface reaction layer on grindability of cast ...

2006-3-1 · Results. For the titanium and gold alloys, grindability increased as the rotational speed increased. There was no statistical difference (p>0.05) in grindability for all titanium specimens either with or without the α-case.Of the titanium metals tested, Ti–6Al–4V had the greatest grindability at higher speeds, followed by DT2F and CP Ti.

Effects of Maceral Compositions of Coal on ...

The role of maceral compositions (vitrinite and inertinite) in the adsorption characteristics of coal has not been fully understood in terms of energy. In this study, using a microcalorimeter, the adsorption heat of maceral compositions for methane is directly measured for five groups of Chinese coal samples with different coal ranks. The results show that the adsorption heat of the maceral ...

Effect of surface reaction layer on grindability of cast ...

2006-3-1 · The high chemical reactivity of titanium with the investments causes a hard, brittle reaction layer (α-case) to form on the cast surface. In our previous study [20], the grindability of cast titanium surfaces was examined before and after the removal of this hardened surface reaction layer and was largely dependent on the machining conditions.
