Abstract

In this study, equiatomic Fe and Co binary alloy was prepared under argon/vacuum atmosphere. 50Fe-50Co alloy was coated with pack boronizing method for the duration of 6 h at 800 °C, 900 °C and 1000 °C. XRD, OM, SEM, SEM-EDS, Vickers hardness measurement devices were applied to characterize, hardness, microstructure, chemical and phase constituents of the synthetized boride layer on Fe-Co alloy. Perfect adhesion of coating to substrate and formation of saw tooth shaped boride layer on the substrate were observed. The coating was composed of Fe2B and Co2B phases. The existence and homogenous distribution of Co in the coating was determined. The coating thickness increased with boriding process temperature. The coating hardness did not vary significantly throughout the thickness of the main boride layer.

Özet

Bu çalışmada, vakum/argon altında hazırlanan atomik olarak eşit miktarda Fe ve Co içeren 50Fe-50Co ikili alaşımı kutu borlama yöntemi ile 800 °C, 900 °C ve 1000 °C’de 6 sa. süre ile kaplanmıştır. Oluşturulan kaplamanın mikroyapısı, faz bileşimi, sertliği, kaplamanın kimyasal bileşimi, X-ray kırınımı, optik mikroskop, taramalı elektron mikroskobu, mikrosertlik cihazlarıyla karakterize edilmiştir. Her üç sıcaklıkta da kaplama tabakasının altlık malzemeye çok mükemmel yapıştığı ve testere dişi morfolojisine sahip borür tabakanın oluştuğu tespit edilmiştir. Kaplama Fe2B ve Co2B fazlarından oluşmuştur. Kobalt elementinin kaplama içerisinde homojen şekilde dağılmış olduğu tespit edilmiş. Kaplama kalınlığı sıcaklığa bağlı olarak artmıştır. Yoğun borür tabakanın sertliği kaplama kalınlığı boyunca değişmemiştir.
