Steel sheet coating compositions in which polymeric resin or ceramic properties are produced by admixing an aluminum coordinate complex and an aluminum resin, a polysilazane as a source of silicon, an organic solvent, an organic synthesis catalyst, and optionally a non-metallic, non-ionic, low-nucleophilic base. The admixed coating is applied to sheet steel prior to hot-stamping in order to inhibit surface formation of iron oxides and to improve steel sheet surface characteristics.

A method for improvement of adhesion and distribution along the surface of coatings using a femtosecond laser is described. The process starts from chemical preparation or cleaning of the target material, surface predetermination, laser irradiation of the surface until a certain surface geometry is obtained, which gives the surface improved wetting properties and chemical surface activation which results in improved adhesion of the coatings on the target material surface. The surface geometries and dimensions to be obtained during irradiation are selected according to the properties of the coating and target material, including the laser parameters and/or the environment to obtain the desired surface geometry, considering possible geometry errors without compromising essential adhesion.
