The disclosure provides for anti-scale deposition coatings for use on surface, such as on oilfield parts. The coating includes a first, sublayer of a metal, ceramic, or metal-ceramic composite, which is characterized in having a hardness in excess of 35 HRC. The coating includes a second, top layer over the first layer, that is a polymer. A surface of the first layer may be conditioned to have a roughened or patterned topology for receipt of and adherence with the at least one top layer. The first layer may provide the coating with hardness, and the at least one top layer may provide the coating with low-friction and anti-scale properties.

This invention relates to a method for producing films of semiconducting material based on the organic-inorganic metal-halide compounds with perovskite-like structure, which can be used as a light-absorbing layer in solar cells, including thin-film, flexible and tandem solar cells, as well as can be applied for optoelectronic devices, in particular, light emitting diodes. The method is comprising the following steps: (a) applying a layer of a precursor, (b) applying a layer of composite reagent, and (c) treatment of the applied layers by the reagent X2 wherein the composite reagent applied in the step b) contains a mixture of AX and X2 reagents, and the film obtained after the step b) contains the seeds of the phase with a perovskite-like structure; the reagent AX is a salt comprising cation A+ and anion X−, and the anion X− is a singly charged anion; the reagent X2 is a molecular halogen.
