This present study aimed to create an Al6061-St52 dissimilar joint and investigate the effect of the transverse speed by the friction stir welding process. Welding aluminum to steel is rugged by fusion methods because of the formation of brittle intermetallic compounds (IMCs). Therefore, to designate optimal parameters, acceptable IMC thickness, and mechanical properties determined. This resear...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The pores of bone tissue that play an important part in regeneration can emulate the areas nanoparticles from porous scaffolds. This work evaluated a novel designed and developed nanostructure surface polyetheretherketone-reduced graphene oxide, calcium hydroxyapatite (PEEK-rGO-cHAp) composite scaffolds four different lattice structures. were fabricated through fused deposition modeling (FDM), ...
OBJECTIVES Bond strength between adhesive systems and the tooth structure is influenced by a large number of variables, which makes the comparison among studies virtually impossible. Also, failure often times propagates into the dental substrate or the composite, deeming the results questionable at best. In spite of the increased popularity gained by micro-tensile and micro-shear tests, in vitr...
