    • PURPOSE:To reduce wear of a snap ring by forming a layer of metallization spray at that end part of a piston pin, made of fiber-reinforced metal, where the snap ring is to be fitted. CONSTITUTION:A piston pin 3 is made of a fiber-reinforced metal, which consists of Al alloy as matrix and long alumina fibers 4 of mean dia. 3mum and mean length 2.5mm. as reinforcement approx. 50% by volume. These long fibers 4 are oriented as stretching in parallel with the axis of piston pin 3. A layer of fusion spray of molybdene 5 is formed at the outside surfaces of the ends of piston pin where a snap ring is fitted, wherein the molybdene layer is provided in consideration of its low attacking characteristic to the snap ring.
    • 目的:通过在活塞销的端部形成一层金属喷涂以减少卡环的磨损,该活塞销由纤维增强金属制成,其中安装卡环。 构成:活塞销3由纤维增强金属制成,由Al合金作为基体和长的氧化铝纤维4构成。 3mum,平均长2.5mm。 作为加固约 50%(体积)。 这些长纤维4被定向为与活塞销3的轴线平行地拉伸。在活塞销的端部的外表面上形成有钼合金层5,其中安装有卡环,其中钼层是 考虑到其对卡环的低攻击特性。

    • PURPOSE:To execute satisfactory insert casting of a whisker-contg. light metal without melt-outflow by subjecting the metallic material contg. needle-like perfect crystal whiskers at a specific ratio and having a prescribed shape to insert casting in the prescribed position of a casting mold by a casting material such as cast iron or cast steel and using a chiller if necessary. CONSTITUTION:The aluminum or aluminum alloy material into which the needle- like perfect crystal whiskers consisting of at least one kind of silicon carbide, Al2O3, BeO, B4C, Si2N4, graphite, Cr, Fe, NI, etc. are incorporated at 2-80vol% or 4-40vol% and is subjected to casting, forging or machining is disposed in the prescribed position of the casting mold. The molten cast iron, cast steel or the like is cast into such mold. The chiller may be used in the dashing spot of pouring if necessary. The whisker-contg. light metal is satisfactorily cast without the melt-outflow.
    • 目的:执行令人满意的镶嵌铸造晶须。 轻金属不会熔融流出,金属材料受到限制。 针状完美晶须以特定比例具有规定形状,以通过铸铁或铸钢等铸造材料在铸模的规定位置嵌入铸造,并且如果需要使用冷却器。 构成:将由至少一种碳化硅,Al2O3,BeO,B4C,Si2N4,石墨,Cr,Fe,NI等组成的针状完美晶须的铝或铝合金材料并入2- 80vol%或4-40vol%,并且经过铸造,锻造或机械加工在铸模的规定位置。 将熔融铸铁,铸钢等铸造到这样的模具中。 如果需要,冷却器可以用在倾倒的尖峰处。 晶须 轻金属不熔融流出而令人满意地铸造。
