Engineering properties of materials includes coefficient of friction COF which are basic in design performance of engineering systems. The COF can be considered as very important in design of handling tools. Various types of handling tools and equipment are used at various stages of disposal and treatment of MSW and COF is one critical property.

The application of tribological knowledge is not just restricted to optimizing mechanical and chemical engineering problems. In fact, effective solutions to friction and wear related questions can be found in our everyday life. An important part is related to skin tribology, as the human skin is frequently one of the interacting surfaces in relative motion.

People seem to solve these problems related to skin friction based upon a trial-and-error strategy and based upon on our sense for touch. The question of course rises whether or not a trained tribologist would make different choices based upon a science based strategy?

In other words: Is skin friction part of the larger knowledge base that has been generated during the last decades by tribology research groups and which could be referred to as Science Friction?

This paper discusses the specific nature of tribological systems that include the human skin and argues that the living nature of skin limits the use of conventional methods.

Skin tribology requires in vivo , subject and anatomical location specific test methods. Current predictive friction models can only partially be applied to predict in vivo skin friction. The reason for this is found in limited understanding of the contact mechanics at the asperity level of product-skin interactions. A recently developed model gives the building blocks for enhanced understanding of friction at the micro scale.

Only largely simplified power law based equations are currently available as general engineering tools. Finally, the need for friction control is illustrated by elaborating on the role of skin friction on discomfort and comfort.

Surface texturing and polymer brush coatings are promising directions as they provide way and means to tailor friction in sliding contacts without the need of major changes to the product. Download to read the full article text.

In all combinations, a stable tensile strength could be obtained under the wide range of welding conditions. In C to steels joints, there was no reaction layer at the weld interface with the exception of a small area at the peripheral region. In C to steels joints, there were reaction layers which consisted of component elements of the base metals. Friction welding is used in many fields because the procedure is easily automated and it is possible to weld dissimilar materials. Recently, various industrial fields have seen an increased demand for dissimilar material joints due to the reduction of weight, resource conservation and energy saving. Joints of pure copper to steels have been used for the electrode for electrical discharge machines and the pipe joint for low temperature.
