摘要： A method for providing a surface finish to a metal part includes both diffusion hardening a metal surface to form a diffusion-hardened layer, and oxidizing the diffusion-hardened layer to create an oxide coating thereon. The diffusion-hardened layer can be harder than an internal region of the metal part and might be ceramic, and the oxide coating can have a color that is different from the metal or ceramic, the color being unachievable only by diffusion hardening or only by oxidizing. The metal can be titanium or titanium alloy, the diffusion hardening can include carburizing or nitriding, and the oxidizing can include electrochemical oxidization. The oxide layer thickness can be controlled via the amount of voltage applied during oxidation, with the oxide coating color being a function of thickness. An enhanced hardness profile can extend to a depth of at least 20 microns below the top of the oxide coating.

摘要： In a method of treating a nitrided/nitrocarburized workpiece, at least a portion of the workpiece is subjected to a first step in which at least one laser beam is moved in at least one pass over the portion, until the surface layer of the portion is transformed in part or in full, and until the distribution of the nitrogen concentration in the diffusion zone is modified. In a second step at least one laser beam is moved in at least one pass over said portion so as to enable the nitrogen concentration in the underlying diffusion layer to be reduced.

摘要： A process and apparatus for forming a hardened outer shell (40) on a refractory metal workpiece (36) preferably heated in a fluidized bed of metallic oxide particles (38) in an environment of an inert gas and a reactive gas with the reactive gas either oxygen or nitrogen. The workpieces (36) are heated in the fluidized bed to a temperature between 800 F. and 1600 F. for a period of over two hours to form hardened outer shell (40) in two layers (42, 44). Outer layer (42) is an oxide or nitride layer having a thickness (T1) between 10 microns and 25 microns. Inner layer (44) is a case hardened layer of the refractory metal having a thickness (T2) between 25 microns and 75 microns. In one embodiment (FIG. 3) workpieces (56) may be cold worked by peening from finely divided metal oxide particles (54) to provide a uniform surface texture for subsequent hardening.

摘要： An apparatus for transferring heat between workpieces and a container (10, 10A). The container (10, 10A) has particulate material (28) occupying a substantial portion of the volume of the container (10, 10A) and the container (10, 10A) is rotated to fluidize the particulate material which contacts the workpieces (30) for transferring heat between the container (10, 10A) and the workpieces (30). The container (10, 10A) is enclosed to provide a sealed volume within the container (10, 10A). A predetermined gas may be provided through an inlet (17, 31A) to the container (10, 10A) and gas may be exhausted from an outlet (16, 133A) from the container (10, 10A). The container may either be heated or cooled as desired.
