“…Diamond coatings on pure-Ti and Ti-6Al-4V alloy through chemical vapor deposition (CVD) are known to improve the tribological performance of the underlying substrates mainly due to their carbide forming tendency (Heinrich et al 1996, Grögler et al 1998, May 2000, Din et al 2018, Zeng and Ning 2021, Oliveira et al 2019, Piotrowska et al 2020. A large mismatch between the coefficients of thermal expansions of diamond (∼1.3×10 −6 /K (Peng et al 1997)) and Ti alloy (∼8.6×10 −6 /K (Chandra et al 1996)), however, results in compressive residual stresses as high as 7GPa, thereby necessitating the coating of thin layers (∼1-2 μm) to avoid self-peeling (Ager, Drory 1993, Rats et al 1995, Scardi et al 1997.…”

Diamond coatings are known to improve the wear resistance properties of substrate materials. This paper aims at analyzing damage behavior of brittle diamond coating deposited on two different ductile substrates, namely pure-Ti and Ti-6Al-4V alloy, subjected to uniaxial tensile loading. In-situ tensile tests were conducted on diamond/Ti and diamond/Ti-6Al-4V coated samples to identify the stressstrain response and the damage behavior of the coating. Surface imaging was performed using scanning electron microscope (SEM). The cross sections were made with the focused ion beam (FIB) gun installed in SEM to observe the coating failure modes. Energy dispersive x-ray and x-ray diffraction analyses were carried out to determine composition. The SEM analysis revealed microcrystalline morphology of the coating and FIB cross-sections showed diamond coating top-layer, TiC interlayer and substrate at the bottom. The XRD and EDX findings confirmed the regions observed in FIB cross-section via chemical analysis. The in situ tensile tests revealed that the coating had undergone failure through crack initiation, fragmentation and delamination. The bucking of the coating under transverse compressive strain of the substrate was also observed. The Ti-6Al-4V alloy caused early cracking and delamination of the coating owing to its higher yield strength and higher rate of stress transfer to the coating. Two-dimensional finite element models were developed to simulate various damage modes, such as cracking, buckling and delamination. Extended finite element method and cohesive damage modeling were exploited to observe cracking and buckling, respectively. Numerical results revealed that the coating was more prone to failure when Ti-6Al-4V, a high yielding less ductile, substrate was used instead of a low yielding highly ductile Ti substrate. Moreover, buckling was found to be the major reason of delamination than bulk cracking. The coating is, therefore, likely to delaminate more severely under the compressive (buckling) than the tensile (bulk cracking) mode of deformation.

“…Recently, improving the mechanical properties of structural metals via pre-tension 10 , pre-compression 11 , pre-rolling 12 and surface mechanical attrition treatment (SMAT) 13 have been extensively reported. It is commonly accepted that pre-deformation greatly affects the deformation behaviors of metals.…”

Mechanical properties and microstructural evolution of Cu-10wt.%Zn and Cu-30wt.%Zn alloys after pre-torsional deformation have been investigated in this study. The results indicated that pretorsional deformation can significantly enhance the strength of both Cu-10wt.%Zn and Cu-30wt.%Zn alloys without changing their shape and size, but with the sacrifice of the ductility. The pre-torsion deformation can introduce gradient hardness and microstructures along the radial direction, with the microstructures along the radial direction in Cu-30wt.%Zn alloy being "dislocations→stacking faults→twins (low density)". The stacking fault energy affects significantly the microstructure along the radial direction.
