Comparison of Moeu27s Scale of Hardness with the Rockwell, Brinell, and Scaleroscope Scales.

摘要

Moeu27s scale of hardness as used in mineralogy is admittedly rather indefinite, and no exact hardnesses are measured. The Rockwell, Brinell, and Scaleroscope machines give quite definite results which may be easily reproduced at any time.The purpose of this investigation is to determine whether any definite relation exists between Moeu27s hardness and the hardness as measured by those machines commonly used for the determination of hardness of metals. If such a relation were found it would provide a more definite and accurate measure of the hardness of minerals.
