“…At the maximum amount of TiO 2 added to the plating bath, the agglomerated particles propagated perpendicular on the cathode surface from big size agglomerations and ended with by particles of smaller size at the final external surface. Magdy et al [42] and Gyawali et al [33] have observed the same phenomenon respectively for MoS 2 reinforcement particles into electrodeposited Ni-W alloy coating and for the incorporation of TiB 2 submicron sized particles into the Ni-W alloy coating. They attributed this roughness to the presence of the coating different microstructures.…”

“…The X-ray patterns of the electrodeposited Ni on copper with the addition of TiO 2 nanoparticles indicate a preferred orientation (texture) of the nickel grain growth due to the lower strain in this direction as indicated by Gyawali et al [33]. The incorporation of TiO 2 nanoparticles has changed the regular growth of crystallites.…”

The objective of this work is to study, on a copper wire, the effect of TiO2-nanoparticles on electrodeposited nickel. Both the microstructure and surface morphology (texture) of the coating were investigated. This deposit is obtained from baths of sulfated electroplating Watts. The Ni-TO2 composite coating is deposited at a temperature of 45 °C. The composite deposit is prepared by adding nanoparticles of TiO2 to the electrolyte. The characterization has been carried out by X-ray diffraction, scanning electron microscopy, microhardness measurements, and electron backscatter diffraction (EBSD). Vickers microhardness was used to characterize the mechanical properties of the electrodeposited nickel. The results showed the effects of the TiO2 on the composition, the surface morphology, and the hardness of the deposited layer. However, there was not an effect of TiO2 nanoparticles on texture.

“…Different reinforcing particles are included to the alloy matrix to increase the strength of the alloy coatings and improve their anticorrosion capability. Studies have been investigated to increase the strength and improve their anticorrosion capability of composite coatings such as Ni-P-Ti 3 C 2 T x @TiO 2 /MoS 2 [10], Ni-B/Al 2 O 3 [11], Ni-W/TiB 2 [12], Ni-W/SiC [13], Ni-B/TiC [14], Ni-B/YZS [15], Ni-Cu/TiN [16], and Ni-W/TiN [17] produced with the distribution of hard ceramic reinforcements in Nibased alloy matrix. Recently, titanium nitride (TiN) reinforcement particles included to the deposited Nibased alloy coatings have become the focus.…”

“…From the development of single-layer coating systems, the design of two or more nano-structured layers forming a composite or hybrid coating have evolved, a so-called multilayer coating, combining the physical characteristics of two or more materials. Multilayer coatings offering, for example, both hard and lubricious properties are reported [7,8] and have now become the standard adopted by the industry [9][10][11].…”

Titanium Aluminium Nitride and Titanium Boride Multilayer Coatings Designed to Combat Tool Wear

2017

The lifetimes and the premature wear of machining tools impact on manufacturing efficiencies and productivities. A significant proportion of machining tool damage can be attributed to component wear. Here, titanium aluminium nitride (TiAlN) multi-layered with titanium diboride (TiB 2) prepared by PVD (Physical Vapour Deposition) sputtering onto H-13 substrates are studied as potential wear-resistant coatings for forging die applications. The TiB 2 content has been altered and two-sets of coating systems with a bilayer thickness either less than or greater than 1 µm are investigated by tribological and microstructural analysis. XRD analysis of the multilayers reveals the coatings to be predominately dominated by the TiAlN (200) peak, with additional peaks of TiN (200) and Ti (101) at a TiB 2 content of 9%. Progressive loads increasing to 100 N enabled the friction coefficients and the coating failure at a critical load to be determined. Friction coefficients of around 0.2 have been measured in a coating containing 9% TiB 2 at critical loads of approximately 70 N. Bi-directional wear tests reveal that bilayers with thicknesses greater than 1 µm have frictional coefficients that are approximately 50% lower than those where the bilayer is less than 1 µm. This is due to the greater ability of thicker bilayers to uniformly distribute the stress within the layers. There are two observed frictional coefficient regimes corresponding to a lower and higher rate of material loss. At the lower regime, with TiB 2 contents below 20%, material loss occurs mainly via delamination between the layers, whilst at compositions above this, material loss occurs via a break-up of material into finer particles that in combination with the higher loads results in greater material loss. The measured wear scar volumes for the TiAlN/TiB 2 multilayer coatings are approximately three times lower than those measured on the substrate, thus validating the increased wear resistance offered by these composite coatings.
