Tailored Spray Coating Based on Splat Morphology Analysis

Ethylene Methacrylic Acid (EMAA) Single Splat Morphology

A single splat is the building block of a thermal spray coating; thus, investigating single splats is essential to understanding thermal spray coatings and their properties. In this study, the morphology of flame sprayed ethylene methacrylic acid (EMAA) splats, deposited at various stand-off distances (SODs) onto glass and mild steel substrates were investigated using a scanning electron micros...

Splat Based Raytracing

Splat based raytracing refers to the use of raytracing techniques to visualise point models. Point models have surfaces represented by unconnected points, rather than triangles. The use of triangles for rendering is efficient as long as the model complexity is low, and each triangle contributes to a significantly large area of the screen. As triangle based models become increasingly complex, th...

Numerical (CFD) Analysis of Thermal Spray Coating Process

Investigation of Hardness, Morphology and Structural Analysis of NiCrBSi Composite Coating on Plain Carbon Steel

High velocity oxy-fuel (HVOF) is one of the emerging technologies among the thermal spraying techniques, for producing uniform and dense coatings, having high hardness and very low porosity. A NiCrBSi alloy coating was prepared with approximately 400µm thick, on the A516 steel by means of HVOF and was analyzed with regard to its detailed microstructures, phase formation, thickness, roughness an...

Corrosion of Cold Spray Deposited Copper Coating on Steel Substrates

The corrosion behavior of copper cold spray coatings on a carbon steel substrate was compared to that of commercially available wrought copper under the conditions anticipated in a nuclear waste repository. Corrosion potential and linear polarization resistance measurements were conducted over 90 d to 120 d in 3.0 mol/L NaCl under anoxic (1) and oxygenated-toanoxic (2) conditions to simulate th...
