High Temperature Self-Lubricating Materials

Lawd – Laser Assisted Wire Drawing

In conventional wire drawing the diameter of a wire or rod-like workpiece is reduced by drawing it through a conical die. Dieless drawing of a wire or a rod is realized by a localized heating of the work piece. As heat source for example an induction coil can be used. Immediately after having passed the heating zone the work piece is cooled to restrict the heat input on very small region. By ap...

Friction and Wear of Self-Lubricating Materials for Hydropower Applications under Different Lubricating Conditions

Self-lubricating bearings in hydropower applications are often lubricated with water under boundary lubricating conditions. Polyhydric alcohols replacing water have shown the potential to reduce both friction and wear. The objective of this work is, therefore, to evaluate the effect of a polyhydric alcohol-based environmentally-acceptable lubricant (EAL) on the friction and wear of self-lubrica...

Optimization of parameters of Anti lock Braking System for use in deep drawing

A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...
