Microplasma spraying of hydroxyapatite coatings on additive manufacturing titanium implants with trabecular structures Mater. Sci.-Pol. (IF 1.1) Pub Date : 2023-03-06 Albina Kadyroldina, Darya Alontseva, Sergey Voinarovych, Leszek Łatka, Oleksandr Kyslytsia, Bagdat Azamatov, Aleksandr Khozhanov, Nadezhda Prokhorenkova, Almira Zhilkashinova, Svitlana Burburska
This paper presents new results of microplasma spraying (MPS) of laboratory-synthesized hydroxyapatite (HA) powder coatings onto trabecular substrates obtained by selective laser melting (SLM) of a certified titanium medical alloy powder. The aim of the study was to establish the possibility of combining the technologies of MPS and additive manufacturing (AM) for the possible production of custom-designed

Effect of shot peening on corrosion resistance of additive manufactured 17-4PH steel Mater. Sci.-Pol. (IF 1.1) Pub Date : 2023-03-03 Aleksander Świetlicki, Mariusz Walczak, Mirosław Szala
Components produced by additive manufacturing (AM) via direct metal laser sintering (DMLS) have typical as-fabricated surface defects. As a result, surface properties of AM products should be modified to increase their strength, anti-wear behavior, and at the same time ensure their high corrosion resistance. Surface modification via shot peening (SP) is considered suitable for AM of engineering devices

Performance optimisation of the turning process along with multi-surface heating process Mater. Sci.-Pol. (IF 1.1) Pub Date : 2023-03-03 D Sathish Kumar, R Thanigaivelan, N Natarajan
Materials that are difficult to cut possess excellent qualities and machinability, though conventional machining techniques require additional energy to circumvent the problems associated with the turning process. In this study, heat-assisted turning of duplex stainless steel (SS) was carried out. Various heating techniques such as infrared (IR)-, ultraviolet (UV)- and hot air (HA)-assisted heating

Static friction of normal and reversed metal–polymer sliding pairs Mater. Sci.-Pol. (IF 1.1) Pub Date : 2023-03-03 Mariusz Opalka
The frictional cooperation of materials with different hardnesses occurs in machine elements in one of the following two variants: simple or reversed friction pairs. For a simple sliding pair, the sliding materials' deformation area (contact area) does not move over the surface of the polymeric element during their interaction. In the case of reversed pairs, the contact surface changes its position

Defect-minimized directly grown graphene-based solar cells Mater. Sci.-Pol. (IF 1.1) Pub Date : 2023-02-07 Yiqian Cui, Jiaqi Wei, Lizhe Jia, Lukai Zhang, Qing Zhou, Yanliang Liu, Yong Zhang, Yu Zhang, Wei Yu
Using plasma-enhanced chemical vapor deposition (PECVD) to directly grow graphene nanowalls (GNWs) on silicon to preparate the solar cells is compatible with current industrial production. However, many defects in the GNWs hinder improvement of the power conversion efficiency (PCE) of solar cells. In this work, we found that the defects in GNWs can be reduced under the condition of keeping the appropriate

Fabrication, microstructure, and machinability of aluminum metal-matrix composites Mater. Sci.-Pol. (IF 1.1) Pub Date : 2023-01-28 S. Kathiravan, R. Thanigaivelan, P. Suresh
Today, researchers across the world focus on sustainable products, and, accordingly, it is now imperative to develop sustainable MMCs. In line with this, ongoing experimental work aims to fabricate aluminum 6061 MMC with ground granulated blast furnace slag (GGBS) and study the micro-structural and machinability characteristics. A liquid state stir casting setup is used to melt aluminum 6061 alloy

Influence of air plasma spraying process parameters on the thermal barrier coating deposited with micro- and nanopowders Mater. Sci.-Pol. (IF 1.1) Pub Date : 2023-01-09 Tadeusz Kubaszek, Marek Góral, Paweł Pędrak
This study investigates the optimal conditions to deposit a thermal barrier coating using micro- and nanopowders in the air plasma spraying (APS) process. The influence of the APS process parameters on the thickness, porosity and hardness of the yttria-stabilized zirconia (YSZ; ZrO2 × 8Y2O3) coatings deposited with a single-electrode plasma gun was determined. The temperature and velocity of melted

Tailoring hydrophobicity properties of polyvinylidene fluoride infused graphene composite films Mater. Sci.-Pol. (IF 1.1) Pub Date : 2023-01-09 Ab Rahman Marlinda, Yusliza Yusof, Nurul Azri Khalisah Aznan, Nurafaliana Berahim, Nor Aliya Hamizi, Leo Bey Fen, Raja Amin Raja Mokhtar, Mohd Rafie Johan
In this work, a synthesis to improve surface wetting resistance composites via infusion of graphene (G) structure into the polyvinylidene fluoride (PVDF) matrices is introduced. Graphene is incorporated into the PVDF matrix with a percentage of 1.0 wt.% up to 2.5 wt.% using simple solvent blending and dry-casting methods. The morphological and structural properties of the graphene infused into PVDF
