in the polymer electrolyte membrane fuel cells (pemfcs), low corrosion resistance and high interfacial contact resistance (icr) are two controversial issues in usage of aisi 316l stainless steel as a metallic bipolar plate. for solving these problems, investigation and development of different coatings and/or surface treatments are inevitable. corrosion behavior and icr of aisi 316l specimens c...

Aerospace applications and energy-saving strategies in general raised the interest and study in the field of lightweight materials, especially on aluminum alloys. Aluminum alloy itself does not have appropriate wear resistance. Therefore, improvement of surface properties is required in practical applications, especially when aluminum is in contact with other parts. In this work, first titanium...

Titanium nitride (TiN), a stable compound with the NaCl structure, has a wide range of properties which find applications in cutting tools, wear resistant parts, semiconductor metallization, and the jewelry industry. However, there are problems with preparing highly adhesive thin films which maintain good properties. Thin films of titanium nitride have been prepared by the Electron Shower (ES) ...

The use of ionized gaseous medium (IGM) to prepare a hard alloy material surface by grinding and its effect on the coating quality was investigated. During grinding, IGM was fed to the cutting area by different methods namely: clockwise (longitudinal), anticlockwise (opposed) and transverse (Cross) feeding, respectively. Thereafter, the samples were coated with a titanium nitride on a modern va...
