The fundamental trigonometric identity establishes that the squared sum of the sine and cosine of an angle equals 1, sin2x+cos2x=1. This identity allows us to express the cosine as a function of the sine and vice versa. In fact, by knowing the value of any tri...

For the first time, a hard wear-resistant multi-layer of TiCrN-TiAlN-TiAlSiN-TiAlSiCN was deposited on carbon steel CK45-based tillage tools to increase their useful lifetime. The layers were deposited by using an arc-PVD method without post-annealing pr
