Carbonitriding of four types of steels, namely, low carbon steel (LCS), medium carbon steel (MCS), low alloy steel (LAS) and high alloy steel (HAS) was achieved using cyanide salt bath heat treatment process. The steels, after preheating, were heated in a diesel fired salt bath heat treatment furnace and then quickly quenched in different media including air, oil and brine. The heat treatment p...

The carbonitriding process, which involves the diffusion of both carbon and nitrogen into the base steel, can be carried out in a salt bath or in a furnace gas atmosphere. It is a modified carburizing process but is mostly done at a lower temperature and for shorter time than carburizing. This process is one of the widely used heat treatments for surface hardening. Nonetheless, there are challe...

Electroless deposition or chemical coating is a well-established industrial technique that gaining popularity. The purpose of the current investigation was to determine how long heat treatment process had on mechanical and corrosion performances Ni-P low-carbon steel. performed steel using salt bath. coated samples were treated at 400°C under atmospheric condition muffle furnace. offers greater...

one of the well-known herbal drugs is henna (lawsonia inermis). according to the components in henna, several beneficial properties (i.e., antimicrobial, anti-inflammation, wound healing, trypsin inhibitory and antioxidant) have been reported. the present study was designed to investigate the effects of two natural substances (sodium chloride and henna extract) on experimental skin lesion due t...

Bath salts are substance of abuse that are becoming more common and are difficult to recognize due to negative toxicology screening. Acute kidney injury due to bath salt use has not previously been described. We present the case of a previously healthy male who developed acute kidney injury and dialysis dependence after bath salt ingestion and insufflation. This was self-reported with negative ...

Bottom-blowing, as widely adopted in electric arc furnace (EAF) steelmaking technology, stir the molten bath by blowing inert gas (Ar, N2) from the bottom of EAF to promote fluid flow and uneven metallurgical reaction in the molten bath. However, for eccentric structure design of electric arc furnace, the problem still exists in EBT(Eccentric Bottom Tapping)area. In this study, by the analysis ...

BACKGROUND The use and abuse of designer drugs has been recognized for decades; however there are many derivatives of compounds that make their way into the community. Abuse of compound(s) known on the street as "bath salt" is on the rise. METHODS We report the case of a 33-year-old man who complained of "flashbacks" and right arm shaking that followed a night of "bath salt" snorting. The act...
