The limit of applicability of the correlation between the ratio of hardness to elastic modulus
(H/E) of coating systems and their wear resistance has been explored. Experimental …

Abstract Development of film materials has been limited by the hardness-fatigue resistance
trade-off. The purpose of the present study was to obtain films with a combination of both …

Adaptive wear-resistant coatings produced by physical vapor deposition (PVD) are a
relatively new generation of coatings which are attracting attention in the development of …

It is important to measure nanomechanical properties of materials for extreme environments
at temperatures that match their operating conditions so that the data are more relevant than …

Machining of hard to cut materials such as hardened steels and high temperature strong
aerospace materials is a challenge of modern manufacturing. Two categories of the …

In this study, AlTiN and AlTiN/AlCrSiN coatings have been synthesized using arc ion plating
for high-speed yet dry cutting applications. The effects of modulation period (from 17.8 to 4.2 …

Advanced nanomechanical testing has been used to evaluate key factors influencing tool
life (1) a plasticity index (PI, the plastic work done/total work done during indentation), at …

A novel laboratory technique, nano-impact testing, has been used to test Ti1− xAlxN (x= 0.5
and 0.67) PVD coated WC–Co inserts at 25–500° C. Cutting tool life was studied under …

We develop a method to accurately and efficiently determine the vibrational free energy as a
function of temperature and volume for substitutional alloys from first principles. Taking Ti 1-x …

Frictional heating results in very high operating temperatures in high speed machining but
the nanoindentation tests used to evaluate novel PVD coating systems for improved cutting …
