Abstract
"MATERIAL ABRASIVO, ARTIGO ABRASIVO E PROCESSO PARA FORMAçãO DE UM MATERIAL ABRASIVO". A presente invenção proporciona um material abrasivo (50) compreendendo uma superfície base possuindo uma pluralidade de formatos piramidais protuberando-se da mesma, sendo a superfície base e as protuberâncias (52) formadas de mesmo material, cada protuberância (52) possuindo uma base substâncialmente triangular, quadrada ou poligonal e lados triangulares que se encontram em um ápice que substancialmente forma uma ponta. As protuberâncias (52) proporcionam bordas planas e cortantes intermisturadas em um padrão tal que o material (50) é capaz de realizar abrasão independentemente da direção de uso. Um revestimento (56) é aplicado para melhorar o desempenho abrasivo e para reduzir a porosidade superficial. Um processo para formação de material abrasivo (50) é também proporcionado."ABRASIVE MATERIAL, ABRASIVE ARTICLE AND PROCESS FOR FORMING ABRASIVE MATERIAL". The present invention provides an abrasive material (50) comprising a base surface having a plurality of pyramidal shapes protruding from it, the base surface and protuberances (52) being formed from the same material, each protuberance (52) having a substantially base triangular, square or polygonal and triangular sides that meet at an apex that substantially forms a point. The protrusions (52) provide flat and intermixed cutting edges in a pattern such that the material (50) is capable of abrasion regardless of the direction of use. A coating (56) is applied to improve abrasive performance and to reduce surface porosity. A process for forming abrasive material (50) is also provided.
