Effect of Implant Surface Microtopography by Hydroxyapatite Grit-Blasting on Adhesion, Proliferation and Differentiation of Osteoblast-like Cell Line, MG-63
… modified surfaces, RBM (resorbable blasting media) surfaces that generate a hydroxyapatite grit-blasting. Methods: First, to produce microtopographically modified surfaces, we made the RBM surfaces using a hydroxyapatite grit-blasting and examined the surface morphology, roughness or …

The Adhesion Strength of a Plasma Sprayed Silicon Bond Coating on a Silicon Carbide Ceramic Matrix Composite
… Surface roughening of metallic components via grit blasting is well documented and understood, but much less is known about preparing ceramic and ceramic composite surfaces for thermal spray coating. Silicon coatings are often used as a bond coating between SiC-based components and EBC top …

Multiaxial Fatigue Life Extension of Steel Elements Using Shape-Memory Alloy/Carbon Fiber-Reinforced Polymer (SMA/CFRP) Patch
… tests informed the evaluation of the grit blasting and power tool cleaning surface preparation methods. Experimental results suggested that the fatigue life extension provided by the SMA/CFRP patch is greater when grit blasting is adopted. Furthermore, they suggest that these benefits …

Surface characterization and adhesive bonding of carbon fiber-reinforced composites
… Methyl ethyl ketone (MEK) wipe, peel ply, grit blast and gas plasma treatments were the pretreatments of interest. Chemical and physical changes which occurred in the cured composite surfaces following pretreatment were characterized with x-ray photoelectron spectroscopy (XPS), ion …

Effect of high velocity oxy-fuel (HVOF) coatings on fatigue behaviour of carbon steel
… to high HVOF flame temperature. From the grit-blasting treatment, the embedment of the grit particles, cracks and notches on the substrate´s surface are the main reasons for the reduction of the tensile strength of the substrate by 9.1%. Similar behaviours are shown by the fatigue …

Microstructural analysis of thermal spray coatings by electron microscopy
… induced by treatments such as grinding or grit blasting, strongly disrupted the spreading of the impacting particles, creating very irregularly-shaped splats with large pores. Spraying conditions also strongly influence splat formation: plasma sprayed splats are fully molten and …

Enabling methodologies for optimal coverage by multiple autonomous industrial robots
… optimal complete coverage for tasks such as grit-blasting and spray painting several problems need to be addressed. One problem is to partition and allocate the surface areas that multiple AIRs can reach. Another problem is to find a set of appropriate base placements for each AIR and to …
