Frente a los problemas de calidad experimentados en producción por muchas empresas cerámicas venezolanas, una de las respuestas consiste en realizar, en los diversos sectores de las minas proveedoras, un análisis no solamente de…
Coloured coatings were obtained on steel by plasma spraying without severe in-flight alteration of pigments, taking profit of the low thermal conductivity of the glassy matrix of glaze particles. Colour matching was studied by mixing 3 different…
The cavitation-erosion resistance of tetragonal zirconia polycrystals with 3 mol% Y2O3 (3Y-TZPs) has been studied in specimens sintered in the temperature range from 1500 to 1590 ºC. The study presents mass loss measurements after exposure to…
The spreading phenomena of particles during thermal spraying are quite difficult to observe given the kinetics of the process. In this work, the splat formation of glass and alumina is theoretically compared, showing that glass transition and…
El efecto llamado “sucio de pared” consiste en la acumulación de gotas de suspensión, en general parcialmente secadas en vuelo, sobre las paredes internas del atomizador. A nivel industrial, este efecto suele alterar la…
Cuando el objetivo de una empresa cerámica es alcanzar una mayor producción, sin invertir en nuevos equipos, su principal preocupación es la optimización del rendimiento de producción de la maquinaria disponible. En…
Milled particles from a (SiO2-CaO-Fe2O3) glass were smoothed by flame spraying, focusing on the elimination of superficial roughness or angularity without reaching complete fusion of the glass. The purpose of this study is the further application to…
