Effects of surface roughness of substrate on properties of Ti/TiN/Zr/ZrN multilayer coatings

Investigations on structural, elastic, thermodynamic and electronic properties of TiN, Ti2N and Ti3N2 under high pressure by first-principles

“…The interesting properties of the transition metal compound, TiN, have been studied with many methods in recent years [10][11][12][13][14][15]. Up to now, TiN is still controversial in high-pressure structural phase transitions [7].…”

Improved tribological properties, electrochemical resistance and biocompatibility of AISI 316L stainless steel through duplex plasma nitriding and TiN coating treatment

“…In scratch tests, the tip experiences a lower contact stress when scraping across a smoother surface. 36 Thus, for a coated surface, the onset of coating fracture is delayed. As a result, the adhesion performance of the TiN-N316s sample (with a surface roughness of 0.046 µm) is better than that of the TiN-N316 sample (with a surface roughness of 0.095 µm).…”

Cu/Ni/Au multilayers by electrochemistry: A crucial system in electronics - A critical review

“…The contact resistance R c can be calculated using the Holm equation [13]: it is proportional to the specific electrical resistance (ρ) and the inverse of the radius of the contact area (a): (1) Therefore, coatings with lower roughness present a higher electrical conductivity. Lower roughness is an especially important factor for Ni barrier layers since the quality and properties of the applied top-coat, especially the porosity content, is directly related to their roughness [36][37][38]. Furthermore, films with spherical surface morphology ( Figure 5) are known to be superior regarding electrical contact purposes [12].…”
