Ni/Ti TOZLARININ GTA YÖNTEMİYLE AISI 1020 ÇELİĞİ YÜZEYİNDEKİ KAPLAMALARININ MİKROYAPI ÖZELLİKLERİ

Bu çalışmada; AISI 1020 düşük karbonlu çelik yüzeyine GTA (gaz tungsten ark) yöntemiyle Ni/Ti tozları kaplanmıştır. Ana malzemenin mikrosertliği (180 HV) iken, yüzey tabakasının mikrosertliği (720 HV) olarak ölçülmüş ve sertlik değerinde önemli ölçüde gelişme sağlanmıştır. Elde edilen kaplama tabakalarının, SEM/ EDS analizleri yapılarak mikrosertlik değerleri kıyaslanmıştır. Metal karbürler Ni-Ti-Fe ve Ni-Ti-C üçlü faz diyagramlarının yardımıyla bulunmuştur.
