The aim of this study was to determine the effect of variations in indentation load and time on the Knoop and Vickers hardness numbers (KHN and VHN) for enamel and dentin. Twenty molar teeth were ...

Indentation Testing Results – Vickers Tip Schott BK7 (borosilicate) glass and Plexiglas (PMMA) were incised with a Vickers tip. As seen in Figure 3, lengthy radial cracks occurred along the ...

We offer a range of indentation types including Vickers, conical and spherical tips. Additionally, the microhardness module is capable of scratch and wear measurements.

The Vickers hardness test is widely used for metal materials. The hardness given by the test is inversely proportional to the ratio of the test force to the indentation area. Since it is inconvenient ...

Phase II’s PHT-6000 nondestructive, portable, ultrasonic hardness tester is suitable for small, large, flat, round, thick or thin workpieces. It can test soft metals, such as copper and brass, and ...

Hardness testing may not be a fundamental physical property, but that does not mean it is not an important property to test and measure. This article discusses methods and the principles behind ...
