摘要
A treatment device is provided for treating a metal object, wherein the treatment comprises at least pickling and phosphating of the object, and, by means of the phosphating, a protective layer is produced on a surface of the object. The treatment device comprises a treatment container for holding the object to be treated and for holding a flowable treatment substance, and a pumping apparatus for circulating at least a portion of the treatment substance. The treatment substance is flowable around at least part of the object to be treated, and is a phosphorus- or phosphate-containing solution. The solution consists of water and a reaction substance, and the reaction substance consists of phosphorus or of a phosphate and at least one additional substance that improves treatment effect. The fraction of the phosphorus or the phosphate in the reaction substance is more than 98 vol % and especially preferably more than 99 vol %.
