WebModern bronze is typically 88 percent copper and about 12 percent tin. Bronze is of exceptional historical interest and still finds wide applications. The earliest bronze artifacts were made about 4500 bce, though use of bronze in artifacts did not become common until much later, in the 2nd millennium bce during the Bronze Age. WebThis paper discusses the results of a study focused on the nature of the interaction of Me-MeN-(Me,Mo,Al)N coatings (where Me = zirconium (Zr), titanium (Ti), or chromium (Cr)) with a contact medium based on the Ni-Cr system. The studies were carried out during the turning of nickel–chromium alloy at different cutting speeds.
