“…Many engineering applications suffer from wear, including transmissions, steering columns, seat frames, fuel tank caps, and so on. In this case, structural failure directly affects the whole component [8]. The heat treatment of magnesium alloys enhances their wear resistance.…”

This article aims to experimentally investigate the effect of heat treatment applied to AZ91 magnesium alloys on wear behavior under different applied load conditions. Apart from as-cast AZ91 alloy, AZ91 alloy samples were subjected to both solid-solution treatment (400°C for 16 hours) and three different aging processes (216°C for 4, 8 and, 12 hours) under three different applied loads (10 N, 25 N and, 50 N). Microstructural, characteristic, hardness, friction coefficient, and wear rate behavior under various applied loads were investigated against each other. The results showed that the wear rate increased in all samples with the applied load, while the friction coefficient decreased. While the highest wear rate was observed only in the solid-solution treated sample, it was observed that the wear rate changed inversely with the aging time. Furthermore, the micro-hardness increased in direct proportion with the aging time. While it was observed that the sample, which was aged for 12 hours, wore 13.6% less under 10 N load than the sample that was only treated with solid-solution, the results showed that the same sample wore about 25% less under 50 N load. The increase in β-precipitates in the structure with the aging period increased the micro-hardness, while the increase in hardness decreased the wear.

“…Çeşitli yüzey kaplama metotları olmakla birlikte, sıklıkla kullanılan metotlardan biri termal sprey kaplama yöntemidir [4]. Uygulamada alev sprey [5], plazma sprey [6], ark sprey [7], HVOF [8] ve soğuk sprey [9] gibi spreyle yüzey kaplama yöntemleri mevcuttur. Bu yöntemler içerisinde HVOF' nin düşük porozite, düşük oksitlenme, yüksek bağlanma mukavemeti, mükemmel korozyon ve aşınma direnci gibi avantajları mevcuttur [10,11].…”

Bu çalışmada, yüksek hızlı oksi-yakıt püskürtme (HVOF) tekniği ile Stellite-1 tozu ile kaplanan AZ91D magnezyum alaşımının aşınma davranışı araştırıldı. Deney numunelerinin aşınma kayıpları farklı yük ve kayma mesafeleri için laboratuvar deneyleri ile ölçüldü ve bu değerler yapay sinir ağları (YSA) modellemede veri seti olarak kullanıldı. Çalışmada kullanılan veri seti 108 adet aşınma kaybı verisinden oluşmaktadır. YSA modellemede giriş parametreleri olarak; numune çeşidi, ortalama sertlik (HV0.1), yüzey pürüzlülüğü (Ra=µm), normal kuvvet (N) ve kayma mesafesi (m) kullanıldı. Çıkış parametresi olarak ise aşınma kaybı (AK) miktarları (mg) kullanıldı. YSA ile aşınma kayıplarının tahmininde başarım oranı 0.9793' dür.

Low alloy and stainless steel are the most used types of iron-based materials world wide. Their use against in machine element work, reclamation, corrosion and wear resistance are still challenging. To overcome this problem, many steel alloys are coated with cermet coatings to protect the parts from wear and corrosion. In the present study, WC-Co and WC-CoCr coatings were applied by means of a high velocity oxy-fuel (HVOF) technique on AISI 304, AISI 1040, and AISI 4340 steel alloys used as substrates. The aim was to investigate surface properties and wear resistance of the coatings and to determine their relationship with the type of coating and substrate. In accordance with this purpose, hardness and thickness of the coatings were measured, sliding wear tests were performed, scanning electron microscope (SEM) images and X-ray diffractions (XRD) were taken, surface roughness and friction coefficients were determined. The results showed that the WC-CoCr coatings had higher hardness and lower thickness than the WC-Co coatings. Maximum hardness was obtained in the WC-CoCr coating applied to AISI 4340 steel, which was also the hardest alloy among those studied. After wear resistance tests, it was revealed that the wear resistance of the WC-CoCr coatings was better than that of the WC-Co coatings for each steel substrate. During the coating, the new phases resulting from the decomposition of the WC phase in the WC-CoCr coatings contributed more to wear resistance than those of the WC-Co coatings. A lower friction coefficient and lower surface roughness of the WC-CoCr coatings during wear were obtained, resulting in higher wear resistance. A WC-CoCr coating on AISI 4340 alloy which has the highest hardness, lowest surface roughness and lowest friction coefficient resulted in the highest wear resistance among all types studied.
