Article
This paper is an investigation into the use of Fe-based alloys as part of wear resistant hardfacing materials in AISI 1.2714 tool steel. Four different weld hardfacing alloys were deposited on 1.2714 steel substrates using tungsten inert gas welding (TIG) process. Wear tests were carried out using a pin-on-disc wear tester at room temperature. Micr...
Article
This paper investigates the effects of process parameters (laser power, scan speed, frequency and fill spacing) on the laser deep engraving of AISI 316 stainless steel. The optimum process conditions for minimization of the surface roughness and maximization of the engraving depth are also determined. An experimental investigation consisting of 108...
Article
The milling of hard materials with a complex shape using conventional methods causes many tool based problems. However, a laser assisted milling process eliminates the tool-based problem because of the small, high intensity beam used. Laser engraving, which is one of milling methods, is an effective process for the machining of difficult to machine...

Bu çalışmada SIMA prosesinde uygulanan deformasyonun, yarı-katı sıcaklığının ve tutma sürelerinin A360 aluminyum alaşımına etkileri incelenmiştir. Mikroyapı incelemeleri için metal mikroskobu ve SEM (taramalı elektron mikroskobu) kullanılmıştır. %22 ön deformasyona tabi tutulan alaşımın 572°C de 6 dakika bekletilmesi ile en uygun küresel tanelerin...
Article
The aim of this study is to investigate the effect of scan speed and frequency on surface roughness and engraving depth of AISI H13 hot work tool steel. The experimental studies were conducted by fiber laser marker machine. The relationship between the parameters is showed that the highest surface roughness and depth values were achieved at lowest...
Article
Thixoforming and related semi-solid processing (SSP) methods require thixotropic materials. One of the many SSP techniques is the cooling slope (CS) casting process, which is simple and has minimal equipment requirements, and which is able to produce feedstock materials for semisolid processing. When the feedstock is reheated to the semisolid tempe...
Article
The effects of laser machining process parameters namely, scan speed and frequency on wear performance of AISI H13 hot work tool steel were investigated in this study. The process parameters are combined with wear process factors and the responses of wear tests were evaluated. The results showed that both friction coefficient and wear rate are affe...
Article
In this study, AISI 8620 steel samples were implanted with nitrogen using plasma immersion ion implantation (PIII) at 320, 380 or 450°C. In addition, PIII was used for simultaneous implantation of carbon and nitrogen into the steel at 380 or 450°C. Treated and untreated samples were studied by wear friction testing, microhardness measurement, atomi...
Article
It has been shown in the literature that plasma immersion ion implantation (PIII) can increase the wear resistance of austenitic stainless steel without losing its corrosion resistance. In this work, the effect of PIII treatment with C ions introduced into the chamber during the process on the tribological properties of AISI 316 L stainless steel h...
Article
Type 304 austenitic stainless steel samples were implanted with nitrogen using plasma immersion ion implantation (PIII) at different temperatures between 350 and 500°C. Treated and untreated samples have been studied by wear-friction testing, microhardness measurement and scanning electron microscopy (SEM). The experimental results indicated that t...
Article
The wear and friction characteristics of zirconium-ion-implanted AISI D3 tool steel have been investigated using pin-on-disc methods. Ion implantation was carried out using a vacuum-arc-based ion implanter to form multicharged zirconium ion beams at a mean ion energy of 130 keV, and the implantation doses investigated were approximately 3.6×1016, 5...
Article
In this study, the tool life of plasma immersion nitrogen-implanted cutting inserts while machining AISI 4140 steel has been investigated. The implantation time was 5 h and the temperature was in the range 320–520 °C. Implantation dose was not, vert, similar2×1018 ions cm−2 for all treatments. Surface topography of the implanted surfaces was obtain...
Article
The aim of this work was to study the tribological benefits of PIII treated austenitic stainless steel by nitrogen ions and/or C ions in a ringer solution, which simulates the environment of the human body. This was achieved by hardness, wear and friction testing, and atomic force microscopy and XRD studies. The results showed that the samples, bot...
Article
The microstructure and mechanical properties of AA5013 aluminum alloys prepared by strain-induced melt activation (SIMA) process were studied to investigate the effects of cold working and heat treatment conditions. The specimens subjected to deformation ratios of 30 and 50% and various heat treatment time and temperature regimes were characterized...

Multicharged, pure, high current and pulsed ion beams of Zr have been extracted from a metal vapor vacuum arc (MEVVA) source and implanted into AISI D3 (C: 2-2,35%, Mn: 0,60%, Si: 0,60%, Cr: 11-13,50%, Ni: 0,30%, W: 1%, V: 1%) tool steel samples at the 3,6.1016, 5.1016 and 1.1017 ions/cm2 doses. The wear resistance and friction coefficient have bee...
