  The tribological properties of Al alloy, alumina coating on Al alloy, DLC coating on Al alloy and duplex alumina/DLC coatings on Al alloy were evaluated by pin-on-disc tribological tests, under a 10 N normal load, m/s sliding speed and 50% RH, using SAE bearing steel (BS) or WC-Co (WC) balls as counterpart materials. Abstract: The diffusion-controlled growth and microstructural evolution at the interface of aluminide coatings and different substrates such as Ni-base superalloys and steel are reviewed. Quantitative diffusion analysis indicates that the diffusion rates of components in the β-NiAl phase increases with the addition of Pt.

  The wear and failure mechanism for multilayered nanostructured coatings has a number of significant differences from the one typical for monolithic single-layered coatings. In particular, while the strength of adhesion bonds at the “substrate-coating” boundary is important for monolithic coatings, then for multilayered nanostructured coatings, the strength of adhesion and cohesion bonds at.

The material utilized in this work was a high strength steel taken from a tensile armour of flexible riser.

The steel wire was a high-carbon steel (C = wt%) with a cross-section of × mm. The steel has a yield strength (YS) of MPa and tensile strength of MPa, as reported : João C.B.

Bertoncello, Leonardo Simoni, Mariana R. Tagliari, Adriano Scheid, Marcelo T.P. Paes, Carl. Press-hardened steel (PHS), used for automotive safety-related structure parts, is sensitive to hydrogen embrittlement due to its martensitic microstructure.

Hydrogen is introduced in PHS during the hot press forming (HPF) process, by an atmospheric corrosion Influence of diffusion coatings on the strength of steel book. In this study, the hydrogen embrittlement behavior of uncoated, aluminized, and galvanized PHSs was investigated.

The Al%Si. In this paper the diffusion behaviour of zinc and magnesium at °C is investigated by annealing Zn-Mg coatings deposited onto steel and subsequently linking the microstructure to the thermal stability and integrity of the system by carrying out crash adhesion by: The as-deposited coating exhibits the adhesion strength of 65 MPa.

It increases to 82 and 88 MPa after 3 min of annealing at and °C, respectively. This corresponds to at least 25 % increase in the interfacial adhesion strength. Both the coatings annealed at Author: S. Sabooni, E. Galinmoghaddam, A.A. Turkin, L.Q. Lu, R.J. Westerwaal, C.

Boelsma, E. Zoestbergen, Y. Electron probe microanalysis was used to characterize nitride diffusion into the tool steel. Scratch testing was carried out to evaluate the bond strength between film coatings (CrN, TiN radical.

In this research, physically vapor deposited Mg Zn and ZnMg Zn bi-layered coatings were annealed at °C for different annealing times to study the origin of the adhesion loss during heat treatment. In the case of Mg Zn bi-layered coatings, it was observed that MgZn 2 and Mg 2 Zn 11 intermetallics are formed during annealing from Zn and Mg by diffusion, which results in a reduction.

During hot stamping and subsequent heat treatment diffusion layer is created between coating and steel. The thickness of this layer is strongly dependent on temperature and time of heat process [3]. We have developed an ion sulphocarbonitriding technique by ion bombardment in the vapour of mixed ammonia-alcohol-carbon disulphide.

In this study the. The influence of coating thickness on lubricated rolling contact fatigue life Friction and wear properties of titanium nitride coating in sliding contact with AlSI 01 steel Wear behaviour of r.f.-sputtered TiN, TiB2 and Ti(B,N) coatings on metal forming tools in a model wear test.

Complex diffusion coating can be achieved through this process, such as chrome calorization as well as chrome-nickel plating. In chemical gas diffusion or out-of-contact gas phase diffusion, the coating material is heated into a gaseous form.

Coatings for turbine blades possess some attractive properties like oxidation and hot corrosion resistance, maintain their strength, cohesion and etc. High temperature damages divide in three general groups: High temperature corrosion type II (–°C), High temperature corrosion type I (–°C), Oxidation (°C and higher).

There are three types of high temperature coating: 1. Thermal diffusion galvanizing, or Sherardizing, provides a zinc diffusion coating on iron- or copper-based materials.

Parts and zinc powder are tumbled in a sealed rotating drum. Around °C ( °F), zinc will diffuse into the substrate to form a zinc alloy.

L stainless steel (FeCrNi) and a Kovar (FeNiCo or 4J29) alloy were diffusion-bonded via vacuum hot-pressing in a temperature range of °C with an interval of 50 °C for Service Property Diffusion Coating These keywords were added by machine and not by the authors.

Influence of HVOF sprayed WC/Co coatings on the high-cycle fatigue strength of mild steel. overlays (hardfacings). Films, coatings, and overlays generally become less cost-effective as production quantities increase, especially when the entire surface of workpieces must be hardened.

The fatigue performance of films, coatings, and overlays may also be a limiting factor, depending on the bond strength between the substrate and the.

Aluminized steel is steel that has been hot-dip coated on both sides with aluminium-silicon process assures a tight metallurgical bond between the steel sheet and its aluminium coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminium alone.

Aluminized steel shows a better behavior against corrosion and keeps the properties of. Ceramic-to-metal heterojunctions have been established to improve high-temperature stability for applications in aerospace and harsh environments. In this work, we employed low-temperature diffusion bonding to realize an alumina/Cu heterogeneous joint.

Using a thin layer of lanthanum-doped titanium (La-doped Ti) to metallize the alumina surface, we achieved the bonding at a temperature range. Therefore, the present paper addresses the development of diffusion coatings on 9% Cr ferritic‐martensitic steels.

The difficulty of coating these materials with conventional diffusion processes arises from the temperature limit above which the conversion of the martensite is accelerated and the mechanical properties would be deteriorated. This chapter reviews the major factors which influence the adhesion of epoxy resins to metals.

adhesion bonds between epoxy coating and carbon steel substrate. adhesion strength at polymer.It seems along with abrasion, dissolution-diffusion could also responsible for the flank wear of TiCN coating.

TiCN coating has higher solubility in steel than TiAlN or Al 2 O 3 coating [2,   High-temperature coatings for superalloys can be divided into three categories: Two of them, diffusion and overlay coatings, are both used to protect a system from oxidation and corrosion.

The third type, thermal barrier coatings, protects the substrate from thermal degradation.
