“…13,14 Traditionally, dicalcium silicate (Ca 2 SiO 4 ) is an important constituent in Portland cement, refractories and heat-resistant coatings. [15][16][17][18] Recent studies have shown that Ca 2 SiO 4 has the potential to be used as biomaterials. Liu et al 19 prepared Ca 2 SiO 4 coatings on the Ti alloys and a bonelike carbonated hydroxyapatite (CHA) layer formed on the surface of the coatings when soaked in SBF for 2 days.…”

“…This process does not exist in the experiment but aids the calculation of the energy release rate. Thus, G ci can be numerically calculated by Eqn (1). An estimate of the mode mixity, ψ, can be obtained from the stress components at the node located near the crack tip using the following equation:…”

“…Thermal spray coatings have been widely used in the industry to improve the durability of engineering components under hostile working conditions such as a corrosive environment, [1,2] abrasion, [3] erosion, [4] high temperature [5] and so on. Unfortunately, interfacial cracks between coating and substrate may initiate at any time due to the residual stress or other driving force resulting in the debonding of the coating from the substrate.…”

In this article, a newly developed MoB-CoCr alloy coating was deposited on 316L stainless steel substrate by high velocity oxy-fuel thermal spraying process. The microstructures and interfacial adhesion of the alloy coating were determined by scanning electron microscopy, X-ray diffraction and three-point bending. The results show that the coating consisted of ternary transition metal boride matrix phases (CoMo 2 B 2 , CoMoB) and a little amount of binary borides (MoB and CrB), the former composed of partially amorphous phase. The formation of the amorphous phase was attributed to the high cooling rates of molten droplets and the proper powder compositions. In the interfacial adhesion measurement, the delamination of the coating is induced during the three-point bending test, and the interfacial fracture toughness is analyzed using a finite element analysis model. The critical load is determined by comparing the load versus deflection curves obtained by finite element analysis under assumed no crack conditions with the experimental data, and other inputs are determined by test.

“…[1][2][3][4][5] For coating/ substrate system, debonding of the coating layer from the substrate can lead to failure of the entire system. So, the bond strength between the coating and substrate is a very important design parameter used in the estimation of the system's lifetime.…”

A novel MoB-CoCr alloy coating was deposited onto stainless steel (2Cr13) substrate using a detonation gun (D-gun) spraying technique. Microstructures of the powder and coating were investigated by X-ray diffraction (XRD), scanning election microscopy (SEM), and transmission electron microscopy (TEM), and a quantitative determination of the adhesion strength of the coating was calculated by combination of modified four-point bending (4PB) test and finite element analysis (FEA) simulation. The results show that the coating mainly consists of ternary transition metal boride matrix phases (CoMo 2 B 2 , MoCoB) and binary borides (MoB and CrB). Nanocrystalline grains with a size of 50-100 nm were observed in the coating. The average energy release rate and phase angle are 191.2 J m À2 and 41.7º, respectively, which show strong bond strength compared to other reported values.
