【工程涂层从入门到精通】Coursera课程学习总结 本课程旨在帮助学习者在机械产品开发过程中，根据产品功能需求，掌握工程涂层的选择与定义方法。课程遵循“为何、何物、如何”的战略，由浅入深地解析涂层应用。 **第一部分：为何 (Why)** 此部分为基础入门，将介绍以下核心概念： * **腐蚀 (Corrosion)**：理解腐蚀的原理及其对材料性能的影响。 * **机械磨损与疲劳 (Mechanical Wear and Fatigue)**：探讨涂层在抵抗磨损和提高疲劳寿命方面的作用。 * **脆化 (Embrittlement)**：分析涂层可能导致的脆化现象及其规避方法。 * **电镀工艺 (Electroplating Process)**：介绍基本的电镀原理和操作。 * **环境议题 (Environmental Topics)**：关注涂层工艺对环境的影响及相关法规。 **第二部分：何物与如何 (What & How)** 此部分将深入探讨各种常见工程涂层的主要技术属性，并结合“如何”实现其功能： * **电镀锌 (Electrodeposited Zinc) 与热浸镀锌 (Hot Dip Galvanizing)**：介绍两种锌基涂层的特性和应用。 * **硬质与装饰性铬 (Hard & Decorative Chromium)**：讨论金属和塑料基材上的铬镀层。 * **工程镍 (Engineering Nickel)**：阐述工程应用中的镍镀层。 * **化学镍 (Electroless Nickel)**：介绍适用于金属和塑料基材的化学镍镀层。 * **电镀银 (Electrodeposited Silver)**：探讨银镀层的导电性和装饰性。 * **电镀金 (Electrodeposited Gold)**：介绍金镀层的耐腐蚀性和导电性。 * **磷化 (Phosphate Conversion Coating)**：说明磷化处理的防腐蚀和涂装基底作用。 * **热喷涂 (Thermal Spray - Plasma, HVOF,...)**：介绍等离子喷涂、高速火焰喷涂等热喷涂技术。 * **阳极氧化 (Anodize)**：重点介绍铝等金属的阳极氧化处理。 * **铬酸盐转化膜 (Chromate Conversion Coating - Alodine)**：说明铝合金等的防腐蚀和预处理。 * **钝化 (Passivation)**：介绍不锈钢等金属的钝化处理。 * **黑氧化 (Black Oxide)**：阐述金属的黑化处理。 **第三部分：何物 (What)** 此部分将对前面介绍的涂层进行总结，并提供一个初步的涂层选择工具。该工具将以目录形式呈现各种涂层及其主要属性，方便学习者进行初步筛选，从而更高效地选择适合特定应用的涂层。 总而言之，本课程通过“为何、何物、如何”的系统性学习，赋能学习者在实际工程项目中，精准地选择和定义合适的工程涂层，以优化产品性能。
This course will provide you practical knowledge at field of engineering coating selection and definition during mechanical development process based on required attributes for product functionality. The course is structured in parts. The logic behind the partition based on understanding that correct application of coating will be achieved by utilizing why, what, how strategy.Why: understand why coating is required/beneficial for the particular application.What: evaluate main attributes of the coating which enables required functionality.How: select most appropriate coating based on required functional attributes & define fully to attain those attributes from the supplier at consistent manner.1. Part 1 (Why)- introduce you to basics of: corrosion, mechanical wear and fatigue, embrittlement, electroplating process and environmental topics.2. Part 2 (What & How) - discussion of main technical attributes of common engineering coatings:· Electrodeposited Zinc (Zn) & Hot Dip Galvanizing ( Zn)· Hard & decorative chromium ( Cr) on metals & plastics· Engineering Nickel (Ni)· Electroless Nickel (Ni) on metals & plastics· Electrodeposited Silver (Ag)· Electrodeposited Gold (Au)· Phosphate conversion coating· Thermal spray (Plasma, HVOF,...)· Anodize· Chromate conversion coating ( Alodine)· Passivation· Black oxide3. Part 3 (What) - summary and preliminary coating selection tool based on main coating's attributes. The tool present coatings with its main attributes as catalogue for more efficient preliminary selection.
