摘要:
A method for the production of an oxide of aluminum based corundum abrasive having a titanium oxide content of less than 0.8 wt. %, wherein the oxide of aluminum is processed by means of a melt or sintering process to form a compact base body for abrasive grains; the base body for abrasive grains is comminuted; the abrasive grain strip thus obtained is graded and the manufactured grain or the graded strip of abrasive grain is subsequently post-treated thermally at temperatures of 800 -1500 DEG C in order to increase the tenacity thereof. The invention also relates to the use of the corundum abrasive grain in abrasives. .

摘要:
The invention relates to a protective layer against wear based on artificial resin according to figure 2. Hard particles (1) having a hardness of at least 6 on the Mohs scale are embedded in said layer, as are compact, round, solid particles (2) which are essentially free of sharp edges and have a hardness of at least 5 on the Mohs scale. The grain size distribution of the round solid particles (2) begins at least with the smallest grain diameter of the hard particles (1) and reaches a maximum of five times the value of the largest hard particle diameter, the average grain diameter of the solid particles (2) being larger than the average grain diameter of the hard particles (1). The invention also relates to a mixture of hard particles and round solid particles for producing a protective layer against wear, a method for producing a protective layer against wear, and the use of one such layer for producing wear-resistant surfaces.
