Abstract

"PEçA DE TRABALHO COM UMA áREA TRIBOLOGICAMENTE SOLICITáVEL E PROCESSO PARA FABRICAçãO DE UMA TAL áREA". A invenção refere-se a uma peça de trabalho (5) com uma área (II) tribologicamente solicitável, que é executada como área corrediça lubrificada por meio de um material intermediário para um contra-corpo se movendo relativamente àquela, a área (11) é provida de uma estrutura formada de uma multiplicidade de bolsas (6). Para garantir uma segura lubrificação mediante pressão hidrodinâmica, as bolsas (6) apresentam uma borda periférica (29) não interrompida e formam uma microcâmara de pressão fechada. A borda periférica (29) é executada como aresta de estrutura rebarbada. As bolsas (6) apresentam em vista do alto uma extensão longitudinal. A área (11) nas regiões portadoras entre as bolsas (6) apresenta uma aspereza funcional.
