During deformation of the sheet metal over a tool, contact occurs only at the peak asperities
of both surfaces. In the contact areas the processed material flows over the tool's surface …

Friction is one of the most important technological phenomena and has a large influence on
the flow characteristics of a deformed material. A strip drawing friction test was used to …

Friction and wear are important when considering the operation and efficiency of
components and mechanical systems. Among the different types and mechanisms of wear …

Ensuring adequate lubrication is a key task in the sheet metal forming process. The
replacement of commonly used synthetic lubricants in metal forming operations by eco …

With the increasing awareness and concerns towards the detrimental impact of mineral-oil-
based lubricants, a step forward is crucial to replace them with benign environment-friendly …

The protection of various tools and components through wear resistant coatings is
imperative in highly efficient and precise industrial manufacturing processes. Especially …

The quality of multi-layer composite coatings (MLCC) directly affects the reliability of
equipment. Ultrasonic C-scan has advantages of non-destructive and high-precision. The …

The numerical simulation of deep drawing processes is state of the art. Beside flow curves
and yield locus, friction coefficients for blank-die contact are the most important, but often not …

The realization of lubricant free forming processes is motivated by an increasing demand for
resource efficiency and higher environmental standards. Further potentials are the reduction …

The paper describes proposition for minimisation of both friction and formation of titanium
protrusions on steel tools during sheet-titanium forming. Such a process poses a significant …
