Etching ink, black stain and bronzing agent, liquid medium on acid basis, especially for titanium and titanium alloys
| Appearance: | light blue, clear liquid |
Application:
The solution supplied ready for use is to be filled into a resistant container made of GRP, HDPE or PP.
Degreasing and inserting the parts:
The parts to be burnished must be degreased before cold burnishing. In the simplest case, this can be done by washing with alcohol.
Blackening effect:
Thorough degreasing of the parts is a prerequisite for uniform blackening. Depending on the material, blackening occurs quickly (approx. 15-30 sec after application). If “NIGRIT Ti” remains on the workpiece too long, loose oxides will accumulate on the surface, which must be removed after the process (expediently with a root brush or similar). If the blackening has not become sufficient, the burnishing process can be repeated after the material has been cleaned. – Here it has been found that more than two burnishing passes hardly show any significant improvement. If there is an irregular colouration after burnishing, this is an indication of insufficient degreasing.
