Keausan adalah sebuah fenomena yang sering terjadi dalam engineering. Keausan bukan hanya proses tunggal, tetapi beberapa proses berbeda yang dapat berlangsung independen atau secara bersamaan. Kompleksitas proses keausan dapat dibaca dengan mengetahui berbagai variabel yang terlibat, yaitu kekerasan, ketangguhan, kelenturan, modulus elastisitas, kekuatan tarik, kelelahan, dan struktur permukaan yang saling bertemu, seperti geometri, temperatur, tegangan, distribusi tegangan, koefisien gesek, dan atmosfer dari permukaan yang aus. Sebuah pahat gagal dengan tiga macam cara yang berbeda; perpatahan nyata, deformasi plastis dan keausan bertahap. Dua cara pertama mewakili kegagalan dini dari pahat. Keausan bertahap adalah hal yang tidak dapat dicegah dan biasanya telah diperkirakan secara alami pada proses pemotongan logam. Kata kunci: "keausan", "kegagalan pahat", "permukaan bahan"Downloads
