A method for forming a polyethylene and alumina nanocomposite coating on a substrate is described. The method may use microparticles of UHMWPE with nanoparticles of alumina to form a powder mixture, which is then applied to a heated steel substrate to form the nanocomposite coating. The nanocomposite coating may have a Vickers hardness of 10.5-12.5 HV.

Articles subject to ice formation during normal use, are described comprising a repellent surface such that the receding contact angle of the surface with water ranges from (90) degrees to (135) degrees wherein the repellent surface comprises a siloxane material. In one embodiment, the repellent surface further comprises a non-fluorinated organic polymeric binder. In another embodiment, the repellent surface comprises a thermally processable polymer and a siloxane material melt additive. Also described are methods of making an article comprising providing an article subject to ice formation during normal use; and providing a liquid repellent surface, as described herein, on at least a portion of the article.
