Tribological properties of carbonized photoresist

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1991
AISI 52100 bearing steel samples were coated with 0.3 to 0.8 μ.m AZ 5210 photoresist by conventional spinning techniques. Ion bombardment with N, Al, and P ions in the dose range of 1016 cm−2 and at an energy of 200 keV was conducted to carbonize the resist and to mix the carbonlike layer with the steel substrate.

Tribological and Mechanical Properties

1980
Publisher Summary This chapter explores the interactions between ion beams and metal surfaces that can lead to changes in mechanical properties. Tribology is a study of friction, lubrication, and wear of engineering surfaces with a view to understanding surface interactions in detail and prescribing improvements in given applications.

Tribological properties of quasicrystalline coatings

Journal of Materials Research, 1993
Coatings of three different compositions (Al65Cu20Fe15, Al64Cu18Fe8Cr8, and Al67Cu9Fe10.5Cr10.5Si3) were realized by various thermal deposition techniques. They were studied in the as-deposited state and after annealing. In view of potential applications, these quasicrystalline coatings were examined from the point of view of tribology: friction and ...

Anisotropic tribological properties of SiC

Wear, 1982
Abstract The anisotropic friction, deformation and fracture behavior of singlecrystal SiC surfaces were investigated in two categories. The first is that in which friction and wear of SiC arises primarily from adhesion between sliding solid surfaces in contact and the second is where friction and wear of SiC occur as a result of the surface sliding ...

Tribological Properties of Epoxy+Silica Hybrid Materials

Journal of Nanoscience and Nanotechnology, 2009
Various amounts of nano size silica particles prepared by a sol-gel process were added to epoxy+ amine systems. We have investigated tribological properties including friction and sliding wear resistance of hybrids so obtained, and also relationships between different tribological properties and surface topography.

Tribological Properties of Drilling Fluids, Use of Polymer Additives to Improve Tribological Properties

Drilling fluids can be clay-based, oil-based, and polymer-based. Polymer drilling fluids reduce friction in the drill string. Polymer drilling fluids also prevent jamming of the drilling tool and perform an anti-corrosion function. Friction is one of the key characteristics of drilling equipment wear. Reducing friction reduces metal wear, which in turn

Tribological Properties of Glass‐Ceramics

Journal of the American Ceramic Society, 1984
Tribological properties of five glass‐ceramics are reported. The materials were tested unlubricated against themselves. Testing was performed using a simulated inertial sample dynamometer. Sliding speeds were between 0.5 and 1.8 m /S with an applied load of 225 N. Average friction coefficients were in the range 0.07 to 0.5.

Tribological properties of titanium alloys

Wear, 1991
Abstract Titanium is often the most cost-effective corrosion-resistant material for applications in the chemical process industry that involve resistance to halides. Unfortunately, there are usually some components in these systems that involve relative sliding-titanium tribosystems — e.g. bolts and nuts, valves, piping connections, etc.
