提供了一种保护制品免受高温、氧化环境损害的方法，同时提供了适用于该方法的合金组合物和等离子沉积靶(108)，以及用于这种环境的制品。该方法包括提供一种基质(110)，提供一种等离子沉积靶(108)，并且通过等离子沉积方法，用靶(108)将保护性涂层沉积在基质(110)上。靶(108)包括大约2-大约25原子％的铬，其余为铝。 A method for protecting an article from a high temperature, oxidative environment is presented, along with alloy compositions and ion plasma deposition targets (108)suitable for use in the method, and an article for use in such an environment. The method comprises providing a substrate (110), providing an ion plasma deposition target (108), and depositing a protective coating onto the substrate (110) using the target (108) in an ion plasma deposition process. The target (108) comprises from about 2 atom percent to about 25 atom percent chromium, and the balance comprises aluminum.
