Wear-resistant coatings improve the machining capability of cutting tools and extend their useful life. However, when a tool needs to be reused, it is mandatory remove existing coating facilitate resharpening recoating. The technique uses electrochemical stripping, which hazardous environment. environmentally friendly pulsed laser stripping causes melting mixing materials, makes difficult separ...

This work proposes the design of laser-textured patterns for development surfaces with high anchor densities capable promoting solid mechanical bonding highly abrasive sintered diamond/carbide-reinforced. Cu-based composite coatings excellent wear resistance. The results show dense and well-adhered onto how higher nucleation TiC/Fe3C on diamond favours its greater within matrix, preventing grap...

Copper-Beryllium alloys have excellent wear resistance and high mechanical properties, they also possess good electrical thermal conductivity, making these very popular in a wide variety of industries, such as aerospace, the fabrication tools for hazardous environments to produce injection molds mold inserts. However, there are some problems processing alloys, particularly when subject machinin...

Fine-grained tungsten carbide copper (WC-Cu) cemented carbide was sintered via spark plasma sintering at 1773K using a fine WC powder with a mean particle size of 0.11 mm. The mechanical properties were compared with tungsten carbide cobalt (WC-Co) cemented carbide and a binderless WC-sintered material. The Vickers hardness and fracture toughness obtained by the indentation fracture method for ...

The dulling of cemented carbide cutting tools after milling five African wood species was studied. The wood specimens investigated varied in high temperature corrosivity (HTC), hard mineral contamination (HMC), and density (D). Attempts to replace the combustion method of evaluating the content of natural HMC in wood with spectral mass analysis methods, such as energy dissipative spectrum (EDAX...
