In laser cladding, a material, usually in the form of powder, is deposited on a substrate. Powder particles are intermingled with inert gas and fed by a powder feeder system on the substrate. Laser is employed to melt the additive material and a small layer of surface of the substrate simultaneously. While the powder is being deposited, the laser melts the powder particles and the melted powder...

Fe60 laser cladding coating was prepared on the surface of 45 steel with assistance alternating magnetic field–mechanical vibration coupling field. The XRD results show that is mainly composed solid solution Ni-Cr-Fe, (Fe, Ni), and Fe-Cr also contains a certain amount Cr2Fe14C hard phase. In process cladding, chemical composition not affected by Under interaction field, liquid metal in molten p...

Laser cladding technology is used to clad the surface layer of H13 mold steel with Ni60A metal powder coating solve failure problem. The study JMatPro software extract and fit thermophysical property parameters substrate material, then ANSYS APDL qualitatively analyze distribution melt pool morphology, nodal temperature versus time course curve residual stress magnitude during laser process. Ba...

We experimentally demonstrate, for the first time, propagation loss reduction via graded-index (GRIN) cladding layers in high-index-contrast (HIC) glass waveguides. We show that scattering loss arising from sidewall roughness can be significantly reduced without compromising the high-index-contrast condition, by inserting thin GRIN cladding layers with refractive indices intermediate between th...

A refractive index (RI) sensor based on a novel fiber structure that consists of a single-mode-multimode-single-mode (SMS) fiber structure followed by a fiber Bragg grating was demonstrated. The multimode fiber in the SMS structure excites cladding modes within output single-mode fiber (SMF) and recouple the reflected cladding Bragg wavelength to the input SMF core. By measuring the relative Br...

This article presents a generalization of the results theoretical and experimental studies on increasing reliability friction units by making antifriction coatings working surfaces with flexible tool. The principle scheme essence method cladding tool (CFT) - shock-frictional forming thin films from various materials surface workpiece elements rotating metal brushes are described.

The fluorescence radiation property at the edge of thin disk crystal is very important to design lasers. In order study this effect, in paper, we established a theoretical model describe process Subsequently, used with indium absorption cladding quantitatively test intensity. significant difference between measured and simulated data can be described as P (probability value) < 0.1 when tempe...
