The hardness, stiffness and toughness of diphasic abrasive materials prepared by sol-gel techniques

Sol-gel techniques have been used to make single-phase alumina and diphasic Ni, NiO and NiAl 2O 4-alumina and AgCl-silica abrasive grains. The hardness, stiffness and toughness of these grains have been measured by indentation methods. The results have been compared with the results of similar mea...

Zusammenfassung:Sol-gel techniques have been used to make single-phase alumina and diphasic Ni, NiO and NiAl 2O 4-alumina and AgCl-silica abrasive grains. The hardness, stiffness and toughness of these grains have been measured by indentation methods. The results have been compared with the results of similar measurements on soda-lime glass and on such current generation abrasives as α-Al 2O 3, α-SiO 2, Cubitron ® and Norzon ® . The new composite NiAl 2O 4-alumina grain has properties that compare well with those of current abrasives.
