Description

一种热喷涂发动机连杆大头内孔耐磨涂层
技术领域
本发明涉及发动机技术领域，尤其是涉及一种热喷涂发动机连杆大头内孔耐磨涂层。
背景技术
传统发动机连杆采用轴瓦方式与曲轴形成滑动摩擦副，轴瓦是现代内燃机中一种重要的滑动轴承，是发动机中非常重要的摩擦易损件，由于制造误差的影响，特别是半径高的影响，在轴瓦与曲轴之间形成的间隙较大，为了形成最佳油膜厚度，存在曲轴和轴瓦进行尺寸分组的情况，从而大大增加了工艺难度。
发明内容
本发明的目的旨在克服现有技术存在的不足，提供了一种可降低制造工艺难度的热喷涂发动机连杆大头内孔耐磨涂层。
为了解决上述技术问题，本发明是通过以下技术方案实现的：
一种热喷涂发动机连杆大头内孔耐磨涂层，由以下质量百分比的材料组成：Sn 4.5-25%，Si 1.2-11%，Cu 0.4-2%，Pb 1-2.8%，Ni 0.7-1.3%，Cr 0.1-0.5%，余量为Al。
一种热喷涂发动机连杆大头内孔耐磨涂层，由以下质量百分比的材料组成：Zn 3-63%，Si 0.2-3.0%，Cu 0.4-4.0%，Pb 1-2.8%，Mn 0.2-0.5%，Mg 0.4-0.7%，余量 为Al。
一种热喷涂发动机连杆大头内孔耐磨涂层，由以下质量百分比的材料组成：Zn2.0-8.0%，Pb 1.0-27.0%，Sn 0.3-11.0%，余量为Cu。
优选的是，所述耐磨涂层的厚度为0.2～0.5mm。
与现有技术相比，本发明具有如下优点：
本发明结构简单，安装方便，尺寸精度高，成本低，连杆外形尺寸可减小2～4mm。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。
