Phosphorus conversion

WebPhosphate conversion coatings are well-known and widely used for applications on steel, zinc and aluminum. 7.19.2 TYPES OF PHOSPHATE COATINGS Phosphate coatings are of three types: (a) zinc phosphate, (b) iron phosphates and (c) manganese chromium phosphates. 7.19.3 PROCESS OF PHOSPHATING WebPhosphorus conversions from Mehlich-3 data require measured values for soil pH, Mehlich-3 P, Ca, and Al. For each test, the range of valid input data is given by a minimum value (min) and a maximum value (max). Also given are the correlation coefficients (r2) for each of the conversion models. The larger the (r2), the more reliable the conversion.
