دراسة الخواص الميكانيكية لأحجار التجليخ المصنعة باستخدام مادة رابطة من مخلفات الزجاج

الملخص EN

The increasing interest of cutting tools come from the development in cutting processes of different engineering materials.

This research includes the study and manufacturing grinding wheels manufacturing from silicon carbide(abrasive material) whose grain size(270 μm) with glass scrap (fluorescent candle) as a binding material.

The fluorescent candles are washed, crushed up to 154 μm particle size.

the binding material is added to silicon carbide with different percentage (10, 15, 20, 25 wt %), then the touches are mixed for 2hr, and pressed at 119 MPa by using steel alloy molds.

Physical (apparent porosity and water absorption) and mechanical (hardness, compression strength, and wear resistance) properties are measured to evaluate the efficiently of the manufactured cutting tools.

The best result was 762 Mpa the hardness of sample SiC 0.25 glass.
