A material transport or heat exchanger system. The material transport or heat exchange system includes at least one component including a base material. The at least one component includes a top functional layer capable of adjusting wetting behavior of the base material. The top functional layer includes carbon and hydrogen, and at least one of a non-metallic element and a semi-metallic element selected from the group consisting of 3rd, 4th, 5th, 6th, and 7th main group of the periodic table of elements, and mixtures thereof. A process for treating a surface of at least one component including a base material of a material transport or heat exchanger system. The process includes forming a top functional layer on at least a portion of the at least one component which is capable of adjusting wetting behavior of the base material. The top functional layer includes carbon and hydrogen, and at least one of a non-metallic element and a semi-metallic element selected from the group consisting of 3rd, 4th, 5th, 6th, and 7th main group of the periodic table of elements, and mixtures thereof.
