Abstract
PURPOSE:To improve abrasion resistance and tape traveling characteristics by constituting the sliding surface of the head ram of a VTR or the like for magnetic tapes of a surface layer of high abrasion resistance and an inner side layer of superior workability on the inner side thereof. CONSTITUTION:The surface layer 8 of the lower drum 3 of a drum device 1 of, for example a VTR having a sliding surface for magnetic tapes, is formed by forging or extruding an alloy contg. 5-15wt% silicon and having <=10mum Al-Si eutectic grain sizes, thereby forming an outside circumferential surface 8' having an abrasion-resistant tape sliding surface 11. Or the surface layer 8 is made by using an abrasion-resistant Ti alloy such as JIS-H-4630 (Japanese Industrial Standards). The inner side layer 10 of the drum 3 is made of an Al alloy (ADC-10 or the like) or the like that is easily worked by die casting or the like. The layer 8 and the layer 10 are formed into one body by press-fitting, shrinkage-fitting, etc. In this way, the workability of the entire part is improved and durability is improved also.
