Abstract

"LâMINA PARA BISTURI TENDO ALTA AGUDEZA E TENACIDADE". A presente invenção refere a uma lâmina para bisturi (20) a qual é feita por deposição de um revestimento (32) sobre uma região afunilada (26) de um substrato (22 que é afunilado com um ângulo agudo incluído de cerca de 10 a cerca de 25 graus a uma borda. O substrato (22) é feito de aço inoxidável de grau cirúrgico endurecido a uma dureza Rockwell C de pelo menos 46 a menos de cerca de 53. O revestimento (32) cobrindo o região afunilada (26) tem uma espessura de cerca de 0,1 a cerca de 2,5 micrómetros e inclui uma primeira camada de revestimento (34) de um primeiro metal, e uma segunda camada de revestimento (36) cobrindo a primeira camada de revestimento (34). A primeira camada de revestimento (34) é preferivelmente zircónio ou uma liga com base em zircónio, e a segunda camada de revestimento (36) é, preferivelmente, nitreto de zircónio, A borda pode ser anatomicamente afiada por aplicação de uma grande voltagem negativa ao substrato (22) relativa à fonte de deposição enquanto uma porção da espessura da segunda camada de revestimento (36) está sendo depositada.
