30 nov 2023 · MRR of diamond film and interface temperature under different pressures at 600 rpm grinding speed. With the rise in grinding pressure, the interface temperature exhibited a further increase. The MRR for the Ti-coated diamond grinding wheel showed a further increase with the rise in temperature, while the MRR for the uncoated diamond grinding wheel remained almost constant.
The crater grinding wear test (DIN EN 1071-6, EN ISO 26423) The crater grinding method can be used to precisely determine the wear resistance of coatings and surfaces. A steel ball wetted with an abrasive fluid and rotating against the specimen grinds a crater into the layer to be tested. The wear coefficient can be calculated from the volume ...
20 giu 2023 · 2.1 Formation mechanism of the electrolytic oxide film of a cast-iron-bonded grinding wheel. According to research by Wu [], in the early stage of the electrolysis of a cast-iron-bonded grinding wheel, the reaction intermediates of oxide film, Fe (OH) 3, and Fe (OH) 2 are formed by the combination of iron ions on the surface of the cast-iron-bonded grinding wheel with hydroxide ions in the ...
The outstanding hardness and wear resistance of diamond materials pose significant challenges in their grinding processes for semiconductor substrate materials. To overcome this, a mechanochemical effect-based approach is used, which employs a grinding wheel comprising titanium (Ti)-coated diamond abrasives. A uniform Ti coating is vacuum-evaporated onto micrometer-scale diamond abrasives. The ...
11 lug 2023 · Adhesive mounting involves the use of a thin layer of adhesive film, typically made of UV-curable or heat-sensitive materials, to attach the wafer to a support substrate, an example is lamination. Lamination refers specifically to the process of attaching a temporary carrier substrate to the backside of the wafer using an adhesive material.
