中文拼音 [jīnzhǔzhùkǒng]
金屬鑄孔
英文

Abstract : porosity of die castings caused by air entrapped into the liquid metal in the shot sleeve is common problem of die csating process
文摘:壓室中氣體捲入金屬液內而造成壓鑄件內部氣孔是壓鑄過程常見的問題。Specification for designation and nominal sizes of openings for woven wire cloth, perforated plate and electroformed sheet for industrial screens
工業篩用金屬絲網布多孔板和電鑄板的篩孔標記和標稱尺寸規范Powder metal is often used instead because it is undesirable or impractical to join the elements through alloying or to produce parts by casting or other forming consists of producing small particles, compacting, and sintering. the squeezing pressure with added heat bonds the metal powder into a strong solid. powdered metals can be ferrous, nonferrous or a combination of ferrous and nonferrous elements
金屬合金一般是無孔隙固體；因為煉制出的合金的實際效果不理想，或者通過鑄造和其他成型方式對小的顆粒進行壓制，燒結出來的產品零件無法滿足需求，因而人們常常使用粉末金屬來代替金屬合金。Metal poured into a mold cavity during the casting process solidifies with the possibility of shrinkage, segregation or porosity, which can prevent an " as - poured " casting from being acceptable for severe applications
在鑄造過程中，澆鑄到模腔內的金屬在凝固過程中可能會產生收縮、分離或氣孔，這些問題使得「澆鑄」鑄件無法被苛刻環境應用領域所接受。Application : grind the surface of wood and metal. lap the hole and surface of work - piece. gind and lap flexible contoured suface, especially concave and convex surface profiles
用途：應用於木材和金屬的表面拋光、工件的內孔、外壁的精磨、用於彎形物的曲面、尤其是凹凸表面和側面的研磨、拋光。適用於鑄鐵、木材、鋼材、有色金屬、塑料。Drilling, gun - drilling, turning, milling of hardened steel, white cast iron, non - iron metals, plastics an synthetics. high wear resistance and edge durability and good toughness properties
對硬鋼、白鑄鐵、非鐵金屬、塑料、合成材料等進行鉆孔、深鉆孔、車削、銑削等加工的牌號。具有高的耐磨性、切面穩定性和好的韌性。Standard grade for turning, drilling, milling, reaming, countersinking of hardened steels, white and grey cast iron light metals, plastics and synthetic materials, al - si - mn - cu - alloys, glass, ceramics, graphite
對硬鋼、白鑄鐵、灰鑄鐵、輕金屬、塑料、合成材料、鋁-硅-錳-銅合金、玻璃、陶器、石墨等進行車削、鉆孔、銑削、鉸孔、穿孔等加工的標準牌號。Abstract : metallic foam or porous materials were developed at the end of the 80 " s and applied to industry at the beginning of the 90 " s. they have excellent physical properties, especially damping characteristis, so they are widely used for vibration insulation, noise elimination, electromagnetic screening and so forth. a description is given of the “ casting and foaming ” method for the fabrication of these metallic foams, and a detailed account of their mechanical and damping properties
