TIG KAYNAK YÖNTEMİ KULLANILARAK AISI 1040 ÇELİKLERİNİN Nİ ESASLI B4C VE SİC TAKVİYELİ SERAMİK TOZLARI İLE KAPLANMASI BULUT, FADİLE ÖZET Bu çalışmada Tungsten Inert Gaz (TIG) kaplama tekniği ile AISI 1040 çeliğin Ni esaslı B4C ve SiC takviyeli seramik tozlarla kaplanması incelenmiştir. AISI 1040 çeliğinin TIG kaplama yöntemi ile kaplanarak yüzey özelliklerinin geliştirilmesi amaçlanmıştır. Böylece AISI 1040 çeliğinin aşınma, sürtünme gibi etkenlere karşı servis ömrü uzatılarak ve bakım maliyetleri azaltılması hedeflenmiştir. Ticari olarak temin edilen AISI 1040 çeliğin üzerine Ni esaslı B4C ve SiC takviyeli seramik tozlarla kaplaması yapılmıştır. Seramik tozlarla kaplanan numuneler başarılı bir şekilde üretimleri yapılmıştır. Oluşturulan kaplama tabakasında B4C ve SiC takviye tozu oranının ve üretim parametrelerinin mikro-yapı ve mekanik özellikleri üzerine olan etkisi incelenmiştir. Kaplanan malzeme ile kaplanma tabakası arasındaki geçişler ve mikro yapısal değişimler Optik mikroskop (OM), Taramalı elektron mikroskobu (SEM), Enerji Dağıtıcı X-Işını Spektroskopisi (EDS) ve X-ışını difraktometer (XRD) işlemleri kullanılarak incelenmiştir. Mekanik özelliklerini belirlemek için ise mikro sertlik ölçümleri yapılmış ve aşınma testleri yapılarak deney parametrelerinin sonuçlar üzerindeki etkileri tespit edilmiştir.; ABSTRACT In this study, the coating of AISI 1040 steel with Ni-based B4C and SiC reinforced ceramic powders with Tungsten Inert Gas (TIG) coating technique was investigated. It is aimed to improve the surface properties of AISI 1040 steel by coating with TIG coating method. Thus, it is aimed to extend the service life of AISI 1040 steel against factors such as abrasion and friction and to reduce maintenance costs. Commercially available AISI 1040 steel was coated with Ni-based B4C and SiC reinforced ceramic powders. Samples coated with ceramic powders were successfully produced. The effects of B4C and SiC reinforcing powder ratio and production parameters on the microstructure and mechanical properties of the formed coating layer were investigated. Transitions and microstructural changes between the coated material and the coating layer were investigated using Optical microscope (OM), Scanning electron microscope (SEM), Energy Dissipative X-Ray Spectroscopy (EDS) and X-ray diffractometer (XRD) processes. In order to determine the mechanical properties, microhardness measurements were made and the effects of the test parameters on the results were determined by carrying out wear tests.

The effect of different cutting parameters on cutting force, tool wear and burr formation in micro milling WCu composite material fabricated via powder metallurgy Erçetin, Ali; Aslantaş, Kubilay In this study, the wears that occurred on the cutting tool edges as a result of being subjected to micro-milling process of W-30%wtCu composite material produced by sintering at 1000 0C were investigated. A series of micro-milling tests were carried out at a constant cutting depth to determine the effect of different feed rates on tool wear. End-mill tools with a diameter of 0.5 mm and two flutes were used in the micro-milling process. Surface images of composite material after sintering and worn surfaces' images of cutting tools after micro-milling process were obtained by utilizing scanning electron microscopy (SEM). Tool wear was followed from digital screen by measuring cutting forces with dynamometer. Suitable cutting speed and feed rate for micro-milling of W-30%wtCu composite material were established by observing tool wear. The results showed that minimum tool wear had taken place at 35 mm/min feed rate and maximum cutting speed. Amount of burr formation was always increased from 1. slot towards 6. slot in all micro milling processes.

An experimental investigation of effect of turning AISI 1040 steel at low cutting speed on tool wear and surface roughness Erçetin, Ali; Usca, Üsame Ali In this study, the effect of different cutting speeds on cutting tool wear and surface roughness was investigated in turning operation. Cylindrical bars of AISI 1040 steel was selected as workpiece materials during this investigations in turning process. The K type coated CVD(Chemical Vapor Deposition) TiAlN ceramic tungsten carbide cutting tools were used in turning of bars. Surface roughness of turned bars and tool wear were accepted as criteria for performance evaluation of these cutters. Tool wear was determined by performing SEM (scanning electron microscopy) and EDX (Energy Dispersive X-ray spectroscopy) analyses after conducting other experimental studies at a constant feed rate. Surface roughness values were also measured after every turning process. The aim of this study was to investigate the influence of cutting speed, especially low cutting speed on tool wear and surface roughness. According to experimental results, decreasing of cutting speed forces the cutting tool more and increasing of cutting speed not only causes more coating wear, but also increase radius of cutting nose. However, the best surface roughness could be obtained in turning process for max cutting speed.
