摩擦堆焊是一种先进技术，可将多种材料固态沉积到相似或不同的材料基材上。本文描述了一种通过摩擦表面将材料沉积到基材上的新方法的研究。在摩擦堆焊技术中，热量完全由摩擦产生。这种金属沉积技术由旋转消耗工具组成，该工具与基材表面摩擦，并且由于工具和基材之间产生的摩擦热和锻造，材料沉积到基材上。材料从消耗工具转移到基材是从工具的侧面发生的，而在传统的摩擦堆焊方法中，材料的转移是从工具的末端发生的。在这项研究中，成功地在 A36 碳钢基材上进行了 A6063 铝合金的单道和双道沉积。为了研究工艺参数对摩擦沉积的影响，将基材分为三个部分，每个部分的施加力不同。对刀具转速、工作台移动速度和法向力等工艺参数进行了实验。使用定制的 JET JMD-18 铣床进行实验。利用粗糙度仪和光学显微镜表征工艺参数对材料沉积的影响。研究结果表明，这种新颖的方法能够产生超薄且光滑的金属沉积物，并具有出色的覆盖率。评估了单道和双道沉积期间的材料消耗，并使用光学显微镜评估了涂层横截面。
Friction surfacing is an advanced technique to create solid-state deposition of wide range of materials onto a similar or dissimilar material substrate. This paper describes the study of a novel method to deposit material onto a substrate by friction surfacing. In the friction surfacing technique, the heat is generated entirely by friction. This metallic deposition technique consists of a rotating consumable tool that rubs against the surface of the substrate, and due to the frictional heat and forging generated between the tool and substrate, material is deposited onto the substrate. The material transferred from the consumable tool to the substrate occurs from the side of the tool, while in the conventional friction surfacing method, the material transfer happens from the end of the tool. In this investigation, the single and double-pass deposition of A6063 aluminum alloy onto an A36 carbon steel substrate was successfully carried out. To study the influence of the process parameters on the friction depositions, the substrate was divided into three sections, while the applying forces were varied in each section. Process parameters such as tool rotational speeds, table traverse speeds and normal force were experimented. A customized JET JMD-18 milling machine was used to carry out the experiments. The influence of process parameters on the material deposition was characterized by means of roughness tester and optical microscope. The results of the study reveal that this novel method is capable to create an ultra-thin and smooth metallic deposition with excellent coverage. The material consumption during the single and double-pass deposition was evaluated, and the coating cross-section was assessed using the optical microscope.
