Frictional behavior of sputtered TiN
Wear, 1987Abstract In this research, reciprocating sliding experiments were conducted on films of sputtered TiN. The primary emphasis was to evaluate the effect of the applied film thickness on the friction coefficient. Other parameters namely, surface roughness, substrate hardness and applied load were also varied and their effects were studied.

Frictional Behavior in Metalworking Processes
Journal of Lubrication Technology, 1970Frictional behavior in metalworking processes between the tool and the workpiece for unlubricated condition is discussed. The primary aim of the work was to develop means to predict frictional behavior in terms of which metal flow can be better understood.

In load bearing articulating joints, friction and wear play an important role in determining the durability and long-term performance of implantable biomaterials. In view of this importance, this chapter introduces the theoretical perspective of friction at tribological interfaces experiencing sliding motion.

The Frictional Behavior of Unlubricated Polyethylene
A S L E Transactions, 1982The unusually low friction and relatively low wear of various types of polyethylene have shown promise for use in naval applications. The investigation concerns friction of polyethylene sliding against itself and against various metal surfaces. The basic materials investigated are all homopolymers having varying degrees of linearity.

Frictional behavior of the correlated chain
Die Makromolekulare Chemie, 1972AbstractThe friction coefficient of linear macromolecules is calculated for the correlated chain model using KIRKWOOD's approximation. This model (proposed by SANCHEZ and FRANKENBERG) incorporates a certain long‐range correlation between the segments of a random chain, and contains two parameters: CF, which depends on this correlation (CF = 1 for a ...

Tunable Friction Behavior of Photochromic Fibrillar Surfaces
Langmuir, 2015Grasslike compliant micro/nano crystals made of diarylethene (DAE) photochromic molecules are spontaneously formed on elastomer films after dipping them in a solution containing the photochromic molecules. The frictional forces of such micro- and nanofibrillar surfaces are reversibly tuned upon ultraviolet (UV) irradiation and dark storage cycles. This

Friction Properties and Frictional Behavior of Rock Separation Planes
1972Since the birth of rock mechanics as a separate branch of science a few decades ago, it has been clear that the laws of continuum mechanics could not be applied to the mechanical behaviour of rock masses near the earth’s surface. The concept of discontinuum mechanics was developed, in which the deformational behaviour of rock masses takes place by ...

Friction and Wear Behavior of Cobalt
Journal of Lubrication Technology, 1975An investigation has been made of the friction and wear behavior of polycrystalline cobalt, over a wide range of rubbing conditions, to establish the general pattern of wear. Evidence has been obtained for the occurrence of three transitions, namely, mild to severe wear at low loads and speeds, severe wear back to mild at higher loads and speeds and a ...

Frictional behavior of commercial graphites
Carbon, 1974Abstract Coefficient of friction of commerical grades of polycrystalline graphites against deoxidized high phosphorus copper has been measured in an inert atmosphere at 10−5 mm Hg pressure. Graphites with large particles have a coefficient of friction of 0·48 at room temperature and of 0·35 at about 1000°C. Finer particle sized graphites have a lower
