Abstract

Additive Manufacturing is one of the revolutionizing technologies of modern manufacturing industry. This technology has time and again proved that any material can be fabricated by it if the right parameters are employed. Other technologies such as powder metallurgy are also dominating the manufacturing industries owing to its potential flexibility in manufacturing complex shapes. In this work, an attempt has been made to fabricate cylindrical components through both the techniques, and their properties are compared. A study on metallurgical properties revealed that both provide similar microstructures, but powder metallurgy yielded better mechanical properties. It has been also observed that the tribological properties are better in additive manufactured components. The reason for this behavior has been studied and discussed.

H20 钢坯的比较研究：增材制造与粉末冶金

摘要

增材制造是现代制造业的革命性技术之一。这项技术已经一次又一次地证明，如果采用正确的参数，任何材料都可以由它制造。粉末冶金等其他技术也因其在制造复杂形状方面的潜在灵活性而在制造业中占据主导地位。在这项工作中，已经尝试通过这两种技术制造圆柱形组件，并比较了它们的性能。对冶金性能的研究表明，两者都提供相似的微观结构，但粉末冶金产生了更好的机械性能。还观察到，增材制造部件的摩擦学性能更好。已经研究和讨论了这种行为的原因。
