Toz Metalürjisi Yöntemiyle Üretilen 17-4 PH Paslanmaz Çeliklerde Mo Miktarının Korozyon Davranışlarına Etkisi
Abstract
Bu
çalışmada, toz metalürjisi yöntemi ile farklı oranlarda molibden ilave edilerek
üretilen 17-4 PH paslanmaz çelik alaşımların mikro yapı ve korozyon
davranışları incelenmiştir. Hazırlanan alaşım tozlar soğuk preslenerek (800
MPa) ham kompaktlar üretilmiştir. Üretilen ham kompaktlar 10-6 milibar vakumda
1300 °C’de 1 saat sinterlenerek, fırın ortamında oda sıcaklığına soğutulmuştur.
Üretilen numuneler taramalı elektron mikroskobu (SEM+EDS), X-ışını kırınımı
(XRD), yoğunluk ve sertlik ölçümleri ile incelenmiştir. Yapılan çalışmalar
sonucunda, 17-4 PH paslanmaz çeliğin yoğunluklarının artan Mo miktarı ile
birlikte arttığı, sertliklerinin ise azaldığı belirlenmiştir.

Effect of Mo Amount on Corrosion Behavior of 17-4 PH Stainless Steels Produced by Powder Metallurgy Method
Abstract
In this study, corrosion
behaviour of 17-4 PH stainless steel alloys was investigated which were
produced by powder metallurgy method by adding molybdenum at different amounts.
Prepared alloy powders were cold pressing (800 MPa) to produce green compacts.
Produced green compacts were sintered in 10–6 mbar vacuum at 1300 °C
for 1 h and cooled down to room temperature in the furnace. Sintered components
were examined by scanning electron microscopy (SEM + EDS), X-ray diffraction
(XRD), and density and hardness measurements. As a result of the studies, it
was determined that density of 17-4 PH stainless steels increased with
increasing Mo amount and the hardness decreased with the addition of amount of
Mo.
