Get this from a library. Friction and wear of plasma-deposited diamond films. [Kazuhisa Miyoshi; United States. National Aeronautics and Space Administration.;]. Reciprocating sliding friction experiments in humid air and in dry nitrogen and unidirectional sliding friction experiments in ultrahigh vacuum were conducted with a natural diamond pin in contact with microwave‐plasma‐deposited diamond films.

Diamond films with a surface roughness (R rms) ranging from 15 to nm were produced by microwave‐plasma‐assisted chemical vapor by: @article{osti_, title = {Adhesion, friction, and wear of plasma-deposited thin silicon nitride films at temperatures to C}, author = {Miyoshi, K. and Pouch, J.J.

The function of hydrogen is also investigated. Hydrogen atoms act as the isolating layer between the carbon films which makes the van der Waals interaction : Tianbao Mao, Hui Wang, Yuanzhong Hu. In this study, we investigated the friction and wear performance of ion-beam-deposited diamond-like carbon (DLC) films ( μm thick) on AISI C steel substrates.

Furthermore, we performed a series of long-duration wear tests under 5, 10 and 20 N loads to assess the load-bearing capacity and durability limits of these films under each by: Book Condition: A copy that has been read, but remains in clean condition.

Regardless of environment (ultrahigh vacuum, humid air, dry nitrogen, or water), ion-beam-deposited diamondlike carbon (DLC) and nitrogen-ion-implanted, chemical-vapor-deposited (CVD) diamond films had low steady-state coefficients of friction (Cited by: The coefficients of friction for the carbon-ion-implanted, fine-grain diamond films were less thanfactors of 20 to 30 lower than those for the as-deposited, fine-grain diamond films.

Superlubricity refers to a sliding regime in which contacting surfaces move over one another without generating much adhesion or friction [1]. From a practical application point of view, this will be the most ideal tribological situation for many moving mechanical systems mainly because friction consumes large amounts of energy and causes greenhouse gas emissions.

The previous chapter discussed the application of conventional IC tools, materials, processes, and fabrication techniques to MEMS. This chapter focuses on the rationale and requirements for the introduction of new materials and processes that can extend the capabilities and applications of MEMS and that are reasonably compatible with IC-based, batch-fabrication.

A diamond-like carbon (DLC) film with a nanostructured surface can be produced in a two-step process. At first, a metal-containing DLC film is deposited.

Here, the combination of plasma source ion implantation using a hydrocarbon gas and magnetron sputtering of a zinc target was used.

Next, the metal particles within the surface are dissolved by an etchant (HNO3:H2O. Diamond films may find application as wear-resistant coatings, wire-drawing dies, coatings for drills, and bearing surfaces. It may also be possible to employ diamond coatings as impact-protection coatings for rain erosion and small-particle impact.

Carbon films with diamond-like properties are very hard and typically have a coefficient of friction which is typically smaller thanaccording to the aforementioned book.

These properties render this material a preferred material for the mechanical protection of paper guidance components in reprographic machinery such as copiers and printers. KrF excimer laser deposition of diamond-like carbon films with germanium interlayers Richard T.
