A method for treating a portion of a metal component by diffusion alloying includes providing a container having at least one open end. The container has a width that is greater than the width of the portion of the metal component to be treated, a thickness that is greater than the thickness of the portion of the metal component to be treated, and a depth that is greater than the length of the portion of the metal component to be treated. According to the method, the portion of the metal component to be treated is placed in the container. A heat-activated alloying powder is placed in the container around the portion of the component to be treated in a layer that extends along the length of the portion of the component to be treated. A non-oxidizing powder is placed in the container adjacent to the alloying powder and around the metal component in a layer that extends to an open end of the container. A cap is provided for each open end of the container to seal the container around the metal component except for gases which are produced in diffusion alloying. A furnace is provided to heat the portion of the metal component to be treated to activate the alloying powder. The container is placed with the portion of the metal component to be treated therein in the furnace, and the furnace is operated to heat the portion of the metal component in the container to a temperature and for a time sufficient to cause diffusion alloying of the portion of the metal component to be treated by the alloying powder.
