“…Erosion caused by sand particles in a flowing solution obviously accelerates corrosion. Studies show that impingement process can introduce residual compressive stress and yield severe plastic deformation [38] that increase the surface roughness and defects density [39]. Consequently, the corrosion rate and the susceptibility to pit corrosion increased as roughness increased [40].…”

Laser Surface Melting (LSM) has the potential to increase the resistance of steels to erosion-corrosion. In this study a submerged jet impingement system containing a brine under saturated CO2 conditions with sand has been used to assess the effect of LSM on the erosion-corrosion resistance of X65 steel. Erosion-corrosion rates under different experimental conditions were deduced based on CFD-simulated results and surface profile measurements. Scanning Electron Microscopy (SEM) was used to observe the morphology of erosion-corrosion damage. The results show that the erosion-corrosion rates at various impact angles can be decreased by LSM. Changes in microstructure, corrosion behaviour and hardness of X65 steel induced by laser treatment were analyzed by using optical microscopy, Transmission Electron Microscopy (TEM), Energy Dispersive X Ray analysis (EDX) together with electrochemical polarization and hardness distribution measurements, in order to clarify how laser treatment imparts the effects on the steel.

From a clinic or medical viewpoint, it is important that the surgical implant retains a combination of high strength (including surface wear resistance), good biocompatibility, and chemical stability. To enable safe interactions between the surgical implants and tissues, surface modification and functionalization are commonly employed.Biological coatings such as TiN and titanium oxides are widely adopted and functionalized with various biological properties such as corrosion resistance, bioactivity, cytocompatibility, and bioconductivity. However, failure of the biological coatings due to the long term corrosion and wear or fretting is the main problem and debris from the materials is the main cause of joint replacement failure. Since the surgical implants are implanted into the human body for a long time, cyclic motions between the surgical implants and human tissues may disrupt the protective biological coatings accelerating corrosion and increasing the risks of immunological response by the leached metallic ions.Therefore, improved metallic biomaterials and the relevant manufacturing techniques are being introduced to meet this demand. Apart from the biocompatibility requirement, metallic biomedical materials also have to meet high standards regarding its performance (functionality, reliability) and selection criteria (cost, manufacturing ability). Up to now, the most often used metallic biomedical materials include stainless steel, cobalt-based alloys, and commercially pure titanium or titaniumbased alloys. However, the implant metallic biomaterials, like all mechanical components, are subjected to degradation and have limited lifetime. Damaged implant requires successive operation to replace worn components and so intensive efforts are made to increase durability of implants metallic biomaterials.For enhancing the mechanical retention, engineered nanostructures on the surface are normally taken to increase effective surface area on implant surfaces (such as both dental and orthopedic applications) to exhibit biological, mechanical, and morphological compatibilities to receiving vital hard/soft tissue, resulting in promoting osseointegration.

“…As a result, manufacturing related preprocessing superficial modifications can be eliminated in the region under cleaning, but a new surface change is imposed. AISI 316 steel plates blasted with Al 2 O 3 or ZrO showed compressive stresses of 400 MPa in surface layers up to 0.080 mm deep, according to Multinger et al [7]. Youssef et al [8] indicated that grinding can induce tensile RS with a value close to the rupture stress of AISI 316L steel.…”

There is no consensus in the literature on the need to remove preprocessing layers from the material prior to the measurement of residual stresses by X-ray diffractometer. Thus, the purpose of this work was to evaluate the residual stresses induced by material preprocessing and its evolution during the preparation of the surface by electrolytic removal. Sample surfaces were pre-processed by grinding and sandblasting and the resulting residual stresses were measured by X-ray diffractometry. At each removal stage, the evolution of residual stresses, hardness and microstructure of the surface were verified. It was concluded that different preprocessing methods can induce surface residual stresses of either tension or compression, reaching different depths. Removal by electrolytic method of the modified layer has shown itself capable of reducing significantly the magnitude of the residual stresses induced by preprocessing. On the other hand, the depth of deformed grains or surface hardness proved to be incapable of predicting the depth of induced residual stresses. Finally, it was discussed whether or not the layers removed by this method reveal the subsurface stresses and if the removal should take place before or after a second processing.
