The types of basic materials used in the experiment are uncoated deep drawn steel DC04 and hot-dip galvanized microalloy steel HX340LAD+Z. During the application of the conversion layer, the changes of the microgeometry parameters of the surfaces were studied with respect to the phosphating time, which was 3, 5 and 10 minutes. The paper also deals with the statistical evaluation of roughness parameters of pre-treated surfaces. The achieved results provide information for other technological operations such as the creation of adhesive joints, where the correct anchoring of the adhesive is important for the load-bearing capacity of the joints.skhttp://creativecommons.org/licenses/by/4.0/microgeometrymetal surfaceconversion layerphosphatingadhesive jointArticlehttps://doi.org/10.26552/tech.C.2024.1.4
