Ceramic composites are suitable materials to improve the surface characteristics of steel. Therefore, in this research, Ni–Cr oxide nanocomposite was coated on 304 stainless steel (SS304) by the electrophoretic approach. The effect of chemical composition and coating parameters (time and voltage) was investigated on morphology, corrosion, microhardness, and wear behavior. The nanocomposites were successfully synthesized in three different compositions (Ni–Cr oxides of 70–30, 60–40, and 50–50). The products were coated on the SS304 in 1, 2, and 3 min and 90, 110, and 130 V. Fourier‐transform infrared spectroscopy, X‐ray diffraction, transmission electron microscope, and field emission scanning electron microscopy analyses were employed to investigate the characteristics of the synthesized powder and resulting coatings. The hardness, wear properties, and corrosion resistance of the coating were studied by microhardness, ball‐on‐disk, electrochemical impedance spectroscopy, and polarization methods. The coatings deposited at 1 min and 110 V were sound and free of microcracks. The wear resistance increased by increasing Cr%, so the 50–50 coating showed the best wear resistance with a friction coefficient of .763 and wear mass of 1.6 mg. However, the coating 70–30 presented the highest microhardness of 180.28 Hv. The coating 60–40 had the best corrosion resistance with a corrosion current density of 5.92 µA/cm2. The corrosion resistance improved for thicker coatings.

“…Liquid-phase techniques involve a number of well-known approaches, which make it possible to obtain composites by combining solid and liquid phases, as well as combining various liquid components. The methods of fluid compression, mechanical and electromagnetic mixing, centrifugal casting, and low-and high-pressure casting are used in this case [10][11][12].…”

A method of synthesizing dispersion-strengthened aluminum matrix composites using a powder metallurgical technique and an in situ method was considered. Methods combination was aimed at ensuring energy efficiency, avoiding vacuum treatment of the reaction medium, and using inert gasses to protect from oxidation. Reinforcement phase precursors are capable of ensuring good wettability of dispersed particles by the molten matrix metal. The options of the methods’ practical implementation are presented by the example of producing aluminum matrix composites filled with various functional particles.

Al esaslı alaşımlar havacılık, otomotiv ve savunma sanayi gibi birçok sektörde kullanılmaktadır. Düşük yoğunlukları ve yüksek özgül mukavemet özellikleri, Al ve alaşımlarını mühendislik malzemeleri olarak kullanılabilir hale getirir. Al esaslı alaşımlar seramik partiküller ile takviye edildiğinde yüksek sertlik ve mukavemete sahip yeni nesil mühendislik malzemeleri olarak kullanılabilirler. Bu çalışmada Al2O3 partikülleri Al-Cu-Mg matrisine ağırlıkça %10, %20 ve %40 oranında mekanik alaşımlama (MA) yöntemiyle takviye edilmiş ve 560 oC, 500 MPa pres koşullarında sıcak pres (SP) yöntemiyle preslenmiştir. MA işleminden sonra partikül boyutu ölçümleri, partikül boyutlarının azaldığını ortaya çıkarmıştır. Al-Cu-Mg ve Al2O3 partiküllerinin MA işlemi öncesi partikül boyutu ölçüm sonuçları sırasıyla 212,434 μm ve 89,208 μm olarak ölçülmüştür. MA işlemi sonrası partikül boyutları %10, %20 ve %40 Al2O3 takviyeli numuneler için sırasıyla 14,224 μm, 13,747 μm ve 10,885 μm olarak ölçülmüştür. %10, %20 ve %40 Al2O3 içeriği ile üretilen numunelerin sertlik değerleri sırasıyla 146,867 HV (0,5), 165,290 HV (0,5) ve 206,843 HV (0,5) olarak ölçülmüştür.
