本発明はアルミニウム製摺動シャフトに関し、さらに詳

。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an aluminum sliding shaft, and more particularly to an aluminum shaft with excellent sliding properties.
［従来技術］
従来より摺動用シャフトとしては、鉄製またはステンレ
ス製のものが使用されており、これらはいずれも表面硬
度が高く相手材鉄との摺動性が良好ではあるが、最近、
摺動用シャフトの軽量化の目的でアルミニウム製のもの
が使用される傾向にある。[Prior Art] Conventionally, sliding shafts made of iron or stainless steel have been used, and although these both have high surface hardness and good sliding properties with the mating material iron, recently,
There is a tendency for sliding shafts to be made of aluminum to reduce their weight.
しかして、摺動部分に当たるアルミニウムが、相手材の
鉄と焼付きを起こし、摺動性が悪い上に摩耗が大きいと
いう問題がある。However, there is a problem in that the aluminum in the sliding part seizes with the steel of the mating material, resulting in poor sliding properties and large wear.
そして、この問題点の対策として、摺動用シャフトとし
てアルミニウム合金で対応しようとすればＡｌ−５Ｉ系
耐摩耗性合金とする必要があるが、この場合表面硬度が
充分でない上に摺動性および耐摩耗性共に不充分であり
、また、塑性加工性かよくなく切削の際に工具寿命が短
く表面仕上がりもよくないという問題がある。As a countermeasure to this problem, if an aluminum alloy is used for the sliding shaft, it is necessary to use an Al-5I wear-resistant alloy, but in this case, the surface hardness is not sufficient and the sliding properties and resistance are poor. There are problems in that the wear resistance is insufficient, the plastic workability is poor, the tool life is short during cutting, and the surface finish is poor.

のである。[Problems to be Solved by the Invention] In view of the above-mentioned problems with aluminum sliding shafts, the present inventor has conducted extensive research and studies, and as a result, the present invention has been developed using aluminum or an aluminum alloy. Excellent sliding performance is achieved by forming the shaft into the shape of the shaft through plastic processing such as drawing, forging, and cutting, and then making only the parts that need to slide smooth and wear-resistant. They developed an aluminum sliding shaft with a

The reason is that a Cu-based intermetallic compound layer is formed.
本発明に係るアルミニウム製摺動シャフトについて以下
詳細に説明する。The aluminum sliding shaft according to the present invention will be described in detail below.
即ち、アルミニウムまたはアルミニウム合金を、抽伸、

−Ｃｕ系の金属間化合物を形成させて、摺動に必要な摺
動性および耐摩耗性を付与させるのである。That is, aluminum or aluminum alloy is drawn,
Plastic processing such as forging and cutting is performed to form the shape of the shaft, and the necessary sliding parts of this shaft are coated with aluminum.
-Cu-based intermetallic compounds are formed to impart sliding properties and wear resistance necessary for sliding.
このシャフトの表面にＡｌ−Ｃｕ系金属間化合物を形成

反応を利用して行うのが簡単であるが、メッキ、溶射等
を適宜選択すればよい。A simple method for forming an Al-Cu intermetallic compound on the surface of the shaft is to use a substitution reaction between cuprous chloride and aluminum, but plating, thermal spraying, etc. may be selected as appropriate. .
