Thanks to its mechanical stability and ability to withstand process temperatures, it allows for an adherent, uniform, and bright coating. The quality of the starting surface directly affects the result. Usually, in addition to mechanical preparation (satin finishing, polishing, etc.), no chemical process is required on the steel surface to ensure resistance to corrosion and oxidation of the processed part.<\/p>\n\n\n\n<p><strong>Gold PVD on steel <\/strong>is particularly widespread in eyewear, fashion accessories, and technical small parts.

In fact, compared to gold, which is an extremely soft metal, these deposits based on metallic nitrides and carbonitrides tend not to become dull over time, maintaining the \u201cmirror-like\u201d effect for a long period.<\/p>\n\n\n\n<p>In everyday practice, both for gold PVD and simulated gold PVD, the <strong>coating resists wear well<\/strong>, but it is not immune to scratches if subjected to constant contact with hard surfaces. Durability depends on<strong> film thickness<\/strong>, <strong>substrate preparation<\/strong>, and <strong>conditions of use<\/strong>.<\/p>\n\n\n\n<p>There are three situations in which the film can be damaged:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>intense mechanical abrasion;<\/li>\n\n\n\n<li>coating thickness that is too low;<\/li>\n\n\n\n<li>substrate porosity or irregularities that compromise adhesion.<\/li>\n<\/ul>\n\n\n\n<p><strong>Under normal conditions of use<\/strong>, eyewear, fashion accessories, technical small parts,<strong> color and brightness are maintained for a long time<\/strong>.

At LEM, we manage both processes: the deposition of ceramic films (simulated gold PVD) that reproduce the gold tone through the use of metallic nitrides, and the production of multilayer systems that integrate a final layer of real 24k gold.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does gold PVD change color over time?<\/h3>\n\n\n\n<p>No, both nitrides and gold are stable and do not darken or change color over time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does gold PVD on steel last longer than on brass and zinc alloy?<\/h3>\n\n\n\n<p>Steel is a particularly compatible substrate with the process and does not require chemical pre-treatments.

The yellow and rose variants make it possible to adapt the color to different stylistic needs, while application on steel offers a good compromise between aesthetics and durability. Although not eternal, the gold finish maintains its properties for a long time, especially when deposition is carried out on properly prepared substrates and with suitable thicknesses.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Gold PVD: durability, colors, rose gold and yellow gold, use on steel and why it does not wear easily.
