Flame spraying compositions exhibiting improved adherence to a variety of substrates are disclosed, as well as articles coated with such compositions. The spraying compositions comprise a granulated mixture of two components: (1) a powdery material selected from the group consisting of powdered metals, heat resistant ceramics, cermets, and resins; and, (2) a ceramic needle fiber such as whisker crystals of SiC or Si3N4. Articles coated with thin films of these coatings exhibit increased thermal and corrosion resistance.
