Plasma is then generated to etch target materials, releasing atoms that deposit onto the substrate and form either a ceramic or metallic layer. Once the coating is complete, the substrate is removed and the process is finished.

Deep cavities are particularly challenging, as it is difficult for the coating to penetrate evenly. Size is another factor\u2014the part must fit inside the vacuum chamber, which has fixed dimensions.<\/p>\n\n\n\n<p class=\"has-text-align-left has-neve-text-color-color has-text-color\">The geometry of the part also affects process efficiency. Flat substrates, such as glass or films, are best suited for flat-geometry systems, while complex or larger shapes require special approaches.

DLC stands for <em>Diamond-Like Carbon<\/em>, which refers to carbon with diamond-like properties. These coatings combine the hardness and durability of diamond with the low friction and self-lubricating qualities of graphite.<\/p>\n\n\n\n<p class=\"has-text-align-left has-neve-text-color-color has-text-color\">By combining diamond-like and graphite-like structures, DLC creates a surface that is both strong and low-friction. The DLC family includes different variations: some are made purely from carbon, others from carbon and acetylene, and some are doped with metals to enhance performance in specific applications.<\/p>\n\n\n\n<p class=\"has-text-align-left has-neve-text-color-color has-text-color\">The choice of the right DLC coating depends on its intended use. Certain DLC types are designed for use with lubricants, while others perform without them. Some are used mainly for decorative purposes, while others provide protection against wear, abrasion, or corrosion.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"padding-right:var(--wp--preset--spacing--30);padding-left:var(--wp--preset--spacing--30);flex-basis:50%\">\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"nv-iframe-embed\"><iframe loading=\"lazy\" title=\"Advamat FAQ: Co jsou to DLC povlaky?\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/drNsKeq5NYo?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/div><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-cover alignfull\" style=\"min-height:600px;aspect-ratio:unset;\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-nv-site-bg-background-color has-background-dim-100 has-background-dim\"><\/span><div class=\"wp-block-cover__inner-container is-layout-flow wp-block-cover-is-layout-flow\">\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div style=\"height:80px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"padding-right:var(--wp--preset--spacing--30);padding-left:var(--wp--preset--spacing--30);flex-basis:50%\">\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"nv-iframe-embed\"><iframe loading=\"lazy\" title=\"Advamat FAQ: Typy DLC povlak\u016f\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/g3NkGw0IaII?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<div style=\"height:24px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-left has-neve-text-color-color has-text-color\" id=\"FAQ11\"><strong>#11 <strong>What types of DLC coatings are there?<\/strong><\/strong><\/h4>\n\n\n\n<p class=\"has-text-align-left has-neve-link-color-background-color has-background\">DLC coatings can be broadly divided into doped and undoped types: <br><strong>Doped DLC coatings:<\/strong> In addition to carbon and residual gases such as hydrogen, these coatings contain metal atoms such as tungsten, chromium, or titanium.
