Hello, I'm Mlkj. I wanted to let you know that I removed one or more external links you added to Physical vapor deposition because they seemed inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page or take a look at our guidelines about links. Thank you.

Please do not add inappropriate external links to Wikipedia, as you did with this edit to Diamond-like carbon. Wikipedia is not a collection of links nor should it be used for advertising or promotion. Inappropriate links may include, but are not limited to, links to personal websites, links to websites with which you are affiliated and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the article, please discuss it on the article's talk page rather than re-adding it. Thank you. Mlkj (talk) 14:20, 26 February 2024 (UTC)
