Polishing methods for metals and alloys.

As before, the traditional abrasive polishing is not only widely used, but also is being improved. An optimization of polishing regimes (contact load, tool feed rate and reciprocating frequency) can significantly increase in the durability of titanium alloys by improving the surface stress state [1]. A theoretical model is proposed to optimize the regimes of the tool movement and prediction of the material removal profile [2]. The duration of mechanical polishing can be markedly reduced using a diamond coated tool deposited from the gaseous phase [3] including for polishing aluminium-silicon alloys [4]. An abrasive polishing of brass is also recommended with a gradual transition from wet regime to dry one which provides a removal of abrasive particles from the treated surface [5]. A new polishing method of zirconium dioxide enables to change in the rheological properties of the suspension [6].
