Abstract

A resistência ao desgaste de foi estudada no aço ferramenta tipoAISI H13 pré- nitretado sob plasma e revestido com TiN. O material foi estudado na condição temperada e revenida para a dureza média de 45 HRC. Amostras foram nitretadas sob plasma a 520oC, em mistura gasosa 5%N2:95%H2, por tempos entre 0,7 e 11 horas, e a seguir revestidas com PVD-TiN, em camadas de ~ 6

Wear resistance of duplex surface treatment was studied on a hot work tool steel AISI H13 after plasma nitriding and PVD-TiN coating. Samples were quenched and tempered before the surface treatments for 45 HRC. Plasma nitriding treatments were carried out at 520oC in gas mixture 5%N2:95%H2 for times ranging from 0,7 to 11 hours. After plasma nitriding the samples were coated by PVD-TIN with thickness ~ 6
