Abstract

In the machine manufacturing industry, machine parts are generally coated after taking their final shape. However, in some cases it may be necessary to reshape the parts obtained in this way with cutting operations.  In such cases, the cutting method chosen is of great importance to carry out the process with minimum damage or without damaging to the coating layer. In this study, Co 2 B nanoparticles synthesized by mechanochemical method were coated to the surface of S235JRC (St37-2) material by CO 2 laser. In order to determine the machinability characteristics of the coated layers, samples were cut with abrasive water jet, wire-electrical discharge machining, abrasive disc and laser, respectively. When the surface properties obtained by the cutting process are evaluated, it is determined that the abrasive disc cutting is the most suitable method for Co 2 B nanoparticle coated S235JRC (St37-2) materials. The characterization and metallographic investigations of the coating layers were carried out with X-Ray diffraction spectroscopy (XRD), scanning electron microscopy (SEM), optical microscope and micro hardness tester.

Özet

Makine imalat sanayinde makine parçalarına genellikle nihai şekil verildikten sonra kaplama işlemi uygulanmaktadır. Ancak kimi zaman parçaların kesme işlemleri ile yeniden şekillendirilmesi gerekebilmektedir. Bu gibi durumlarda kaplama tabakasına zarar vermeden ya da en az zararla işlemin gerçekleştirilebilmesi için seçilen kesme yöntemi büyük önem arzetmektedir. Bu çalışmada, mekanokimyasal yöntemle sentezlenen Co 2 B nanopartiküller kullanılarak CO 2 lazeri ile S 235JRC ( St37-2 ) malzeme yüzeyine kaplama yapılmıştır.  Kaplanmış numunelerin işlenebilirlik karakteristiklerini belirleyebilmek amacıyla numuneler sırasıyla aşındırıcı su jeti, tel erozyon, aşındırıcı disk ve lazerle kesilmiştir. Kesme işlemleri ile elde edilen y üzey özellikleri değerlendirildiğinde, Co 2 B nanopartikülleri kullanılarak kaplanmış çelik malzemenin işlenmesinde en uygun yöntemin aşındırıcı diskle kesme olduğu tespit edilmiştir. Kaplama karakterizasyonu ve metalografik incelemelerde X ışını kırınımı (XRD), taramalı elektron mikroskobu (SEM), optik mikroskop ve mikrosertlik test cihazı kullanılmıştır.
