The composition of different Mg alloys is known to affect their current capacity, potential, and anode efficiency. Many alloying elements have been used in attempts to improve the electrochemical properties of magnesium anodes. Significant improvements of electrochemical properties have been achieved by controlling the adverse effects of impurity elements such as Fe, Ni, Cu with alloying elements. Out of many elements, Ca is considered as a very effective element that can improve the electrochemical properties of Mg-alloys because of its relatively low potential in comparison with specified elements such as Mn, Al, Zn in high Mn alloys or AZ63 alloys with the effect of grain refining. Ca has recently been used as a common inhibitor for the ignition of molten Mg alloys. However, the viscosity of pure Mg is markedly increased with increasing Ca content. Ca is responsible for making the casting of Mg alloys from Mg melt difficult at desirable pouring temperatures. In the present study, the effect of Ca addition on the viscosity and electrochemical properties of Mg-Ca alloys is investigated. Viscosity as well as electrochemical data will be correlated with chemical composition of impurities, and the microstructural change before and after Ca is added.","PeriodicalId":194215,"journal":{"name":"Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials.

The size, shape, texture and color of bubbles in a froth image is very important information for optimizing flotation. To determine these parameters, the bubbles in a froth image have to be delineated first. Due to the special characteristics of froth images and a large variation of froth image patterns and quality, it is difficult to use classical segmentation algorithms. Therefore, a new segmentation algorithm was developed to delineate every individual bubble in a froth image. A new segmentation algorithm based on valley-edge detection and edge tracing has been developed. In order to detect bubble edges clearly and disregard the edges of the white spots, the algorithm just detects valley-edges between bubbles in the first step. It detects each image pixel to find if it is the lowest valley point in a certain direction. If it is, the pixel is marked as an edge candidate. Before this procedure, to alleviate noise edges, an image enhancement procedure was added to filter out the noise pixels. After valley-edge detection, the majority of edges are marked at one time, but some small gaps between edges, and noise still exist in the image. To reduce the noise, a clean up procedure was developed. To fill the gaps, an edge tracing algorithm was applied, in which, edges are smoothed into one pixel width. Endpoints and their directions are detected, and edge tracing starts from the detected endpoints. When a new valley-edge pixel is found, the algorithm uses it as a new endpoint, and the valley-edge tracing procedure continues until a contour of a bubble is closed. The segmentation algorithm has been tested on images from Pyhasalmi mine in Finland and Garpenberg mine in Sweden. The processing speed of the algorithm is much faster than for normal morphological segmentation algorithms. The processing accuracy is better than that of manual segmentation result.","PeriodicalId":194215,"journal":{"name":"Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials.
