Shore Hardness is nothing but a measure of the hardness of a given material or how resistant it will be to permanent indentation. It is measured by the depth of indentation that is created on the material with a specified force. The measuring instrument is actually a durometer, but Shore Hardness is named after its inventor Albert Shore

Indentation hardness tests were performed on thick, fine-grained, electro-formed deposits of copper and nickel using Knoop, Vickers, and Berkovich indenters. The latter type of indenter was used for shallow penetrations 85-1750nm, and results are reported in terms of nanoscale hardness NH numbers

2020-7-10As soon as we receive our raw material we test then with PMI machine. The same test is repeated at the final staged of inspection. This report can be submitted to the customers if mutually agreed upon. Hardness testing. We perform hardness test on our raw or finish material if required by our customers or if specified in quotation

Sintered aluminium oxide Al2O3 is a synthetic ceramic material.In nature Al2O3 occurs in form of corundum, the second hardest mineral after diamond. Due to its hardness Al2O3 often is used as abrading medium. When producing sintered aluminium oxide, pressed alumina powder is

Using test methods such as scanning electron microscopy, hole-drilling strain-gage method, semiautomatic and automatic image analysis, and X-ray diffraction, parameters like elastic moduli, impact strength, ductility, hardness, residual stress, and grain sie are measured

2020-7-18A refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are inorganic, nonmetallic, porous, and heterogeneous. They are typically composed of oxides of the following materials silicon, aluminium, magnesium, calcium, and irconium

2020-7-17A superhard material is a material with a hardness value exceeding 40 gigapascals when measured by the Vickers hardness test. They are virtually incompressible solids with high electron density and high bond covalency.As a result of their unique properties, these materials are of great interest in many industrial areas including, but not limited to, abrasives, polishing and cutting tools, disc

2017-9-26process. To reduce the cost of primary slurry material, some alternate refractory material like, alumina, silica, used with ircon to enhance properties. The hardness test of the casted samples and micro-examination under binocular metallurgical microscope has been done to study the micro-characteristic evaluation
