BACKGROUND: A review of the literature showed that the core competencies needed by newly graduated Chinese nurses were not as of yet undocumented. OBJECTIVE: To develop a psychometrically sound instrument for identifying and measuring the core competencies needed by Chinese nursing baccalaureate graduates.
A&P here. Zinc chromate is used as a primer on aluminum surfaces as a conversion process to inhibit corrosion. Since nearly all modern aircraft skins and structures are made from aluminum, this compound and its derivatives are the most common primers seen in aircraft manufacturing.
Chromate conversion coatings on zinc plated steel are often used as a final finish to retard the formation of white or gray products of corrosion of the zinc during environmental exposure, and also prevents surface discoloration from fingerprints and perspiration as the result of handling.rom this consideration alone, application of a chromate coating is advisable. Figure 1 In general, chromates are applied by immersing the zinc-plated parts in a solution containing dichromate, or chromic acid and an activator (usually, nitrate, sulfate, chloride, formate, or fluoride).
