Formation of a hybrid coating by the use of plasma nitriding and hard chromium electroplating on the surface of H11 hot work tool steel
Abstract: Formation of a hybrid coating by the use of plasma nitriding and hard chromium electroplating on the surface of H11 hot work tool steel was investigated. Firstly, specimens were plasma nitrided at a temperature of 550 °C for 5 hours in an atmosphere of 25 vol. % H2: 75 vol. % N2. Secondly, electroplating was carried out in a solution containing 250 g/L chromic acid and 2.5 g/L sulp...
متن کاملDry Wear Behavior of 42CrMo4 Steel/ZrO2 Composite Prepared by Pressure-Less Infiltration Method
The aim of this research was to study the wear behavior of 42CrMo4 steel/ZrO2 composite with 10 and 30 ppi performed ceramic and compare it with the un-reinforced steel under different applied loads. The composite specimens were obtained by pressureless infiltration of the melt into a preformed ceramic of zirconium oxide. The effect of applied load on the specimens wear behavior was ...
متن کاملFriction and wear behaviour of ceramic-hardened steel couples under reciprocating sliding motion
The friction and wear behaviour of ZrO*-Y203, Zr02-Y203--Ce02 and ZrQ--A1203 composite ceramics against hardened steel AISI-52100 were investigated using a pin on plate configuration under reciprocating motion. The reproducibility of the results was examined in this configuration. Wear characteristics were separated into system and material contributions. Under the conditions used, all the cera...
متن کاملFriction and wear behaviour of tool steels sliding against 22MnB5 steel
Boron steels are used in hot stamping process due to their good mechanical properties. During the stamping process, the dies are exposed to aggressive conditions including adhesive wear, abrasion, thermal stresses and fatigue. In the present work, QRO 90 and UNIMAX slid against 22MnB5 steel in four conditions: with and without hardening treatment and, with and without Al–10%Si coating, in order...
متن کاملDuplex Surface Treatment of AISI 1045 Steel via Plasma Nitriding of Titanized Layer
In this Study, surface of medium carbon steel (AISI 1045) was modified by titanizing followed by plasma nitriding. Titanizing was performed using pack cementation method, in a pack mixture of ferrotitanium, ammonium chloride and alumina, at 1223 K for 45 and 180 min. Plasma-nitriding was conducted at two temperatures of 803 and 823 K for 5 h, in a gas mixture of 75%N2+25%H2. The samples were c...
