Description
上記目的を達成するための本発明の摺動部材用高力黄銅合金は、
（１）質量比で、１７％以上２８％以下の範囲内のＺｎ、３％以上１０％以下の範囲内のＡｌ、１％以上４％以下の範囲内のＦｅ、０．１％以上４％以下の範囲内のＣｒ、０．５％以上３％以下の範囲内のＳｉ、残部がＣｕ及び不可避的不純物からなり、
（２）母相がβ相の単相組織を呈するとともに該β相にＦｅ−Ｃｒ−Ｓｉ系金属間化合物が分散した組織を呈することを特徴とするものである。
The high-strength brass alloy for sliding members of the present invention for achieving the above object is
(1) By mass ratio, Zn within a range of 17% to 28%, Al within a range of 3% to 10%, Fe within a range of 1% to 4 %, 0.1% to 4% Cr in the following range, Si in the range of 0.5% or more and 3 % or less, the balance is made of Cu and inevitable impurities,
(2) The parent phase exhibits a β-phase single-phase structure and a structure in which an Fe—Cr—Si intermetallic compound is dispersed in the β phase.
図１は本発明の高力黄銅合金を使用した板状体の形態をなす摺動部材（すべり板）１を示す平面図である。高力黄銅合金の摺動部材基体２の一方の表面（摺動面）には、その厚さ方向に凹んだ複数個の凹部４が形成されている。この凹部４は、該摺動部材基体２の表面の面積に占める開口部の面積の総和が１０〜４０％の割合となるように形成される。 FIG. 1 is a plan view showing a sliding member (sliding plate) 1 in the form of a plate using the high-strength brass alloy of the present invention. A plurality of recesses 4 that are recessed in the thickness direction are formed on one surface (sliding surface) of the high strength brass alloy sliding member base 2. The concave portion 4 is formed so that the total area of the openings in the area of the surface of the sliding member base 2 is 10 to 40% .
