Nickel- and Nitrite-Free Pretreatment for Car Bodies
1997-10-1 Nickel- and nitrite-free phosphating. The nickel- and nitrite-free phosphating process is based on layer-forming cations of zinc, manganese and copper, with copper used only in traces and hydroxylamine serving as an accelerator. To prevent the formation of "white spots" on galvanized steel, the phosphating solution contains complex fluorides.

Photoluminescence properties of cuprous phosphide
Herein, we prepared the Cu 3 P through phosphating process and studied its photoluminescence properties in detail. We observed that the presence of cuprous oxide and annealing enhanced the fluorescence emission of Cu 3 P. We proposed that the mechanism of the PL enhancement is due to the band bending and the trapped carriers in the space charge
