Abstract In this study, the influence of Al2O3 particle amounts on the mechanical, tribological, and corrosion properties of the composite NiP-Al2O3 coating was evaluated. AISI 4140 steel was coated with NiP through an autocatalytic bath with the addition of Al2O3 particles maintained in suspension by mechanical stirring. Following, the coated samples were annealed at 600 °C to increase the hardness and to create an interdiffusion layer, which improves coating adhesion and corrosion resistance. The coating surface was characterized by SEM/EDS, XRD, microhardness, wear resistance, and corrosion tests. The results showed that the coating particles' amount depends on the bath agitation speed, the sample orientation during the deposition, and the volume of Al2O3 particles in the bath composition. Also, the number of particles in the coating affects the deposition kinetics, the thickness of the interdiffusion layer, which affects the wear and corrosion resistance.

CrNx film was widely used in mechanical engineering field because of its excellent anti-wear and corrosion resistance properties. While most of research was focused on mechanical properties, little attention had been paid to the corrosion resistance and residual stress of CrNx film . In this paper, CrNx films were deposited on silicon wafer (100) and iron substrate by unbalanced magnetron sputtering system (UBMS) at different N2 flow. Then the structure, thickness, residual stress, micro-hardness, wear-resistance and anti-corrosion properties of CrNx films were investigated. The results showed that the phase composition of CrNx films transformed from Cr, single phase Cr2N, Cr2N and CrN coexist to single CrN with the N2 flow rate increasing. The CrNx films composed with Cr2N phase, which deposited at 6 sccm N2 flow, had the highest microhardness and had higher compressive residual stress. Whereas the CrNx films with CrN and Cr2N phase coexist had the best wear and corrosion resistance.

Wear And Corrosion Resistance

The wear and corrosion resistance of Ni-based niobium carbide (NbC) coatings were investigated via scanning electron microscopy, energy dispersive spectrometry, particle size analysis, X-ray diffraction, electrochemical polarization, electrochemicl impedance spectroscopy, digital microhardness testing and wear testing. The results showed that the substrate was mainly composed of a γ-Cr (Fe) solid solution, and the composite coating was composed of FeNi, NbC, and Ni. In addition, the hardness of the coating increased gradually with increasing NbC content. The optimal corrosion resistance and wear resistance of the coating were realized at an NbC content of 20%.

Wear And Corrosion Resistance

H13 steel is often damaged by wear, erosion, and thermal fatigue. It is one of the essential methods to improve the service life of H13 steel by preparing a coating on it. Due to the advantages of high melting point, good wear, and corrosion resistance of Mo, Mo coating was fabricated on H13 steel by electro spark deposition (ESD) process in this study. The influences of the depositing parameters (deposition power, discharge frequency, and specific deposition time) on the roughness of the coating, thickness, and properties were investigated in detail. The optimized depositing parameters were obtained by comparing roughness, thickness, and crack performance of the coating. The results show that the cross-section of the coating mainly consisted of strengthening zone and transition zone. Metallurgical bonding was formed between the coating and substrate. The Mo coating mainly consisted of Fe9.7Mo0.3, Fe-Cr, FeMo, and Fe2Mo cemented carbide phases, and an amorphous phase. The Mo coating had better microhardness, wear, and corrosion resistance than substrate, which could significantly improve the service life of the H13 steel.
