It can add brightness, luster and appeal.</li><li class="ql-indent-1">It also provides excellent adhesion properties for subsequent coating layers, which is why nickel is often used as an ‘undercoat’ for other coatings, such as chromium.</li></ul><p><br></p><h3><strong>Applications:</strong></h3><ul><li class="ql-indent-1"><strong>Aerospace</strong>: Nickel alloy coatings are used on aircraft and aerospace components to provide protection against corrosion and wear, as well as to improve the durability and lifespan of the parts.</li><li class="ql-indent-1"><strong>Automotive</strong>: Nickel alloy coatings are used on automotive parts to protect against corrosion and wear, as well as to improve the durability and lifespan of the parts.</li><li class="ql-indent-1"><strong>Food Processing: </strong>Used on food processing equipment to protect against corrosion and to provide a non-stick surface.</li></ul><p class="ql-align-center"><br></p><h1 class="ql-align-center"><strong>PRELIMS NOTES:</strong><a href="https://sunyaias.in/notes/prelims-2023" rel="noopener noreferrer" target="_blank" style="color: rgb(0, 102, 204);"><strong>CLICK HERE</strong></a></h1>
