92 Cladding of alloy 625 to copper substrate and investigation tribological behavior of clad layer Mansour Rahimi Email address Mansour rahimi@ma iut ac ir Date of Submission June 20 2017 Department of Materials Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M S Language Farsi Supervisor Mehdi Salehi Professor Email salehi@hotmail co uk Graduuate Cordinate Masoud Atapoor Assistant professor Email atapoor58@gmail comAbstractToday high temperature wear is a serious problem in many industrials According to fasterkinetic of surface at high temperature wear behavior at high temperature can becompletely different from wear at room temperature At mold of continuous casting due tocontacts surfaces of copper with molten steel high temperature wear happen In thisproject Inconel 625 was cladded to pure copper with GTAW process Microstructure ofweld overlay consists of Nb rich secondary phase at primary phase Microhardness ofInconel 625 at the top of weld measured using Vicker s microhardness employing load of50 gf Wear behavior of copper and Inconel 625 against H13 tool steel was investigatedwith high temperature pin on disk machine at 0 1 m s linear speed Wear behavior of purecopper at 5N vertical force from room temperature to 50 C and wear behavior of Inconel625 was studied at 5 10 20 and 30 N vertical force from room temperature to 550 C Comparing wear behavior of substrate and Inconel 625 revealed that cladding 400 improved wear behavior Low mechanical properties poor adherence of oxide layer tosubstrate and insufficient support causes to poor wear behavior of copper Worn surfacesof Inconel 625 studied using SEM equipped with EDS analyzer Wear debris investigatedwith SEM and XRD At room temperature abrasive and adhesive wear causes to weightloos of Inconel 625 At temperature up to 350 C the glaze layer formed on worn surfacesand weight gain of Inconel 625 increased According to XRD the oxide layer produced inthe worn surfaces was Fe2O3 Fe2O4 NiFe2O4 and NiCrFeO4 Keywords high temperature wear glaze layer oxide chemistry wear map
