摘要
PURPOSE:To provide a highly wear resistant blade body at a low cost by spraying thermally and coating a ceramics on the surface part of a base material for a blade having a cutting edge-shaped end edge to form a hard layer and forming the cutting edge part consisting of the ceramics to the blade edge. CONSTITUTION:The cutting blade 3 and receiving blade 6 of a tea leaves picker are manufactured by machining the end edge of a flat plate-shaped base material (a) for a blade to finish the same to a required blade edge c' shape and spraying thermally and coating a ceramic material on the surface part including the end edge to form a uniform hard layer (b) and providing a cutting edge part (c) formed of the ceramics to the edge c'. A non-rusting metal such as a stainless steel or aluminum or a metal having high toughness such as a metal subjected to a rust treatment on the surface is used for the material (a) and non-oxide ceramics such as silicon nitride and silicon carbide or oxide ceramics such as alumina and zircon are used for the layer (b). The thickness of the layer (b) is made about =0.1mm..
