A removable partial denture (RPD) represents the prosthetic solution for a partially edentulous patient who desires to have replacement teeth for functional and aesthetic reasons, and who cannot have a “bridge” (a fixed partial denture) for any number of reasons, such as a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or due to financial limitations.
So, in non-treated state (fig.2a) the structure consists in non-homogeneous molybdenum – chromium - cobalt solid solution and interdendritic eutectic, with very big grains.

Eddy current flaw detector in actual use would affect by a number of factors, such as changes of ambient temperature, surface hardness, uneven mechanical rotating and jitter.
In physical properties, ultrasonic method can measure the thickness, material hardness, hardened layer depth, grain size, level and flow, residual stress and plastic bonding strength.
However, for a large number of insulators detection workload is too difficult to carry out, and this methods must be used in good weather and the insulator surface condensation conditions, otherwise it’s easy to miscarriage a good insulator to poor quality insulators.

The Ni foam surface is smooth and grain boundary is clear and easy to distinguish.
From Fig.5 (a)-(c), with the extension of etching time, the number of pores in the strut is increased and the size of the pores becomes larger, until the surface of strut becomes rough.
The elongated time contributes to the more number of pores and the large specific surface area.
