Plasma Spraying Process

Plasma spraying is a technique which is used to apply coatings to metallic substrates for a variety of purposes, including hardfacing, corrosion resistance and thermal barrier applications. Almost all of the applications of this somewhat esoteric fabrication technique involve materials in hostile environments and the integrity of the coatings is of paramount importance: the effects of process variables on such properties as adhesive strength, cohesive strength and hardness of the substrate/coating system, however, are poorly understood.Briefly, the plasma spraying process involves forming a hot plasma jet with a maximum flame temperature of approximately 20,000K and a gas velocity of about 40m/s. Into this jet the coating material is injected, in powder form, so it is heated and projected at the substrate surface. Relatively thick metallic or ceramic coatings may be speedily built up using this technique.

Homicide Case

Many factors affect the solvability of homicides, including body disposal location and time between death and recovery. The aim of this exploratory study was to probe a number of spatiotemporal variables for trends across a subset of solved homicide case data from 54 North American serial killers, active between 1920 and 2016 (125 solved cases) to identify areas for further research. We investigated murder site and body disposal site as location variables with eight subcategories across eight discrete time series, seeking insight into how these factors may affect the early stages of an investigation and (therefore by inference) solvability. The findings showed that bodies recovered after 48 hours are more likely discovered outdoor while those discovered within 24 hours, within the victim’s residence. This has implications for the ability to recover forensic evidence when bodes are located after a prolonged time since death as well as in more hostile environments.
