In this study, the surface properties of a W360
ISOBLOC as hot work steel was investigated in
respect to mechanical and microstructural aspects. Three were three different
sample-plasma gun nozzle distances (30, 40 and 50 mm) and three different pulse
number (5,10 and 15) were chosen for the
surface modification at a constant battery capacity of 800 mf. After pulse
plasma surface treatment, the modified surface layers were examined using an
optical microscope. The SEM and EDS analyses were applied to surface on
samples. It was observed that surface treatment affects the formation of a new
structure. XRD analyses was done. The new phases were formed such as FeN, Fe2N,
g- Fe, W3O which is located in the modification layer. The
samples were also subjected to micro-hardness measurements. It was found that
the hardness values of modified surfaces are 4-6 times higher than that of the
untreated samples.

Pulse plazma
prosesi bir modifikasyon yöntemidir. Bu çalışmada; sıcak iş takım olan W360 ISOBLOC çeliğinin
yüzeyleri pulse plazma sistemi ile modifiye edilmiş ve bu yüzeylerin mekaniksel
ve mikroyapısal özellikleri araştırılmıştır. Deneysel çalışmalarda üç farklı
nozul mesafesi (30mm, 40mm, 50mm) ve pulse sayısı (15, 10, 5) kullanılmıştır.
Modifiye edilen numunelerin optik mikroyapı fotoğrafları çekilmiş ve
modifikasyon tabaka kalınlıkları ölçülmüştür. Pulse plazma prosesinin
uygulandığı parametrelerin değişiminin modifikasyon tabaka kalınlığını ve
yapısını etkilediği belirlenmiştir.
Modifikasyon tabakasından alınan x-ışını analizlerinde FeN, Fe2N, g- Fe piklerine
rastlanmıştır. Çelik yüzeylerine SEM ve EDS analizleri uygulanmıştır.
Mikrosertlik ölçümlerinde mesafeye ve pulse plazma parametrelerine göre değişen
sertlik değerleri elde edilmiştir. Modifikasyon işlemi uygulanmadan çeliğin
sertlik değeri 4-6 kat artmıştır.
