In general, these alloys are not susceptible to galvanic corrosion, and their ease of polarization tends to minimize adverse galvanic effects on other metals or alloys. Because of the ease with which...

... depths can be difficult to measure. Therefore, sputter rates are often specified relative to a known sputter rate on a reference material, such as Ta 2 O 5 on tantalum metal or thermally grown SiO 2 on single-crystal silicon. Practical maximum profile depths are on the order of a couple micrometers...
