the absence of marked ridges and valleys upon the cuesta surfaces,

Occasionally you may find damage to the finished surface.

To render the titanium body (10) better suited for implantation, the outer surface (12) is grit blasted and then bulk etched with an etching acid to produced an etched area (16) which is free of the oxide layer (14).

For this purpose, the current collector foil comprises an acid-etched or alkali-etched surface.

An automatic manufacturing apparatus processes a substrate (14) having etched patterns to be filled with metallization.

A film substrate (5) is bonded to the etched surface, and the support (3) provisionally bonded to the surface of the glass substrate (1) is peeled off.

Etched surface from a high purity (99.9998%) aluminium bar, size 55×37 mm

The treatment pressure and the mixing ratio (CH2F2/O2) are used as parameters for setting a plasma etching apparatus in accordance with the set value of the uniformity in an etched surface.

The present invention provides a method for treating a surface of a cutting tool, the method including blasting the surface of the cutting tool using a granular abrasive and brushing the blasted surface of the cutting tool.

A method is described of selectively etching a silicon substrate in small local areas in order to form columns or pillars in the etched surface.

Once the surface has been stripped, be sure to identify any small imperfections, such as holes, poorly driven nails, mould or splinters.

The determination can be carried out on a representative section of the blast-cleaned surface or, if direct observation of the surface is not feasible, on a replica of the surface.

The determination can be carried out on a representative section of the blast-cleaned substrate or, if direct observation of the surface is not feasible, on a replica of the surface.

On the same stripped area, three other non-adjacent one-meter channel samples gave 0.73, 0.58 and 0.56% Nb2O5.
