Lazer kaplama<\/strong> gerekli \u00f6zellikleri elde etmek i\u00e7in alt tabakan\u0131n y\u00fczeyini kaplamak i\u00e7in lazer teknolojisinin kullan\u0131lmas\u0131d\u0131r. Lazer kaplaman\u0131n ala\u015f\u0131m sistemi temel olarak demir bazl\u0131 ala\u015f\u0131m, nikel bazl\u0131 ala\u015f\u0131m, kobalt bazl\u0131 ala\u015f\u0131m ve sermet i\u00e7erir. Demir bazl\u0131 ala\u015f\u0131m tozunun lazerle kaplanmas\u0131, k\u0131smen a\u015f\u0131nmas\u0131 ve kolay deforme olmas\u0131 gereken par\u00e7alar i\u00e7in uygundur.

Nikel bazl\u0131 ala\u015f\u0131m kaplamalar, k\u0131smi a\u015f\u0131nma direnci, \u0131s\u0131 korozyon direnci ve termal yorulma direnci gerektiren bile\u015fenler i\u00e7in uygundur ve gerekli lazer g\u00fc\u00e7 yo\u011funlu\u011fu, demir bazl\u0131 ala\u015f\u0131mlar\u0131n kaplanmas\u0131ndan biraz daha y\u00fcksektir. Kobalt bazl\u0131 ala\u015f\u0131m kaplamalar a\u015f\u0131nma, korozyon ve termal yorulma direnci gerektiren par\u00e7alar i\u00e7in uygundur. Seramik kaplama, y\u00fcksek s\u0131cakl\u0131kta y\u00fcksek mukavemete, iyi termal stabiliteye, y\u00fcksek kimyasal stabiliteye ve geni\u015f bir matris malzemesi yelpazesine sahiptir.
