Micro Structural Characterization of Thermal Spray Coating on Stainless Steel AISI 316 L

Thermal spray coating process is a surface modification technique in which a coating material like cermets, metallic, ceramic and some other materials in form powder are feed into a torch or a gun, the powder inserted into torch will be melted by high temperature developed by torch. Coating thickness can achieve by applying multiple layer of melted coated material. This paper aims at the study of micro structural characterization of thermal spray single layer and multi-layer coatings. Coatings on the substrate were followed by Scanning electron microscopy and X-ray diffraction to know the different phases present in the coated as well uncoated SS 316L. By seeing SEM result it’s found that single layer coating is not done properly. As compared to SEM result of single layer coated AISI 316 L multilayer SEM results is more accurate, there is no crack on the coating surface and there is much less porosity in the multilayer coated sample. AISI 316L contain Nickel (Ni) and Chromium (Cr) as major phase.

Manufacturing of Cement from Egg Shell

Effective deployment of bio-waste has been given importance in our society for environmental and economic concerns. Reclamation of eggshell from hatcheries, home, bakeries and industries is an efficient and cost productive way to reduce waste disposal and prevent serious environmental pollution. Egg shells waste constitutes essential organic and inorganic materials that can be composted with other materials for enhancing the pre-existing property. The major concern in any civil sector is efficient construction with minimal cost investment. Cement is one of the pivotal components for construction. It is the backbone to the infrastructure development. Rapid infrastructure developments ensued in high demand for raw materials worldwide that resulted in huge imbalance between demand and supply. However, cement plants are the source of few harmful compounds like nitrogen oxide (NOx), Sulphur dioxide (SO2) and Carbon monoxide (CO) which can cause serious health defects and also affects our environment as well. The cement manufacturing sector is the third largest reason for total pollution in our environment. In spite of all these there is a huge demand for the cements for the development of a country. This increase in demand, led to search for alternative raw materials from enormous waste product which is both efficient and cost productive began. In this work, calcinations of chicken eggshells with different ingredients were carried out and the chemical composition of the resultant product was analyzed.

Coating thickness can achieve by applying multiple layer of melted coated material. This paper aims at the study of mechanical characterization of thermal spray single layer and multi-layer coatings. Coatings on SS 316L is followed by the wear test .It has been found that the wear rate of base metal i.e. SS 316L is more than single layer and multi layer coatings. The multilayer has shown the maximum resistance to the wear rate.

A Review Study of Thermal Spray Coatings for Corrosive Wear

Thermal spray coating process is a surface modification technique in which a coating material likes cermets, metallic, ceramic and some other materials in form powder are feed into a torch or a gun, the powder inserted into torch will be melted by high temperature developed by torch. Coating thickness can achieve by applying multiple layer of melted coated material. This papers aims at the review of various coating techniques used for the corrosive wear applications. Thermal sprayed thick (from 50 to 3000 μm) coatings, including cold spray coatings are more and more used in industry for the following reasons: (i) They provide specific properties onto substrates which properties are very different from those of the sprayed coating; (ii) They can be applied with rather low or no heat input to substrates (allowing for example spraying ceramics onto polymer substrates); (iii) Virtually any material that melts without decomposition or vaporizing can be sprayed including cermets or very complex metal or ceramic mixtures, allowing tailoring coatings to the wished service property; (iv) Sprayed coatings can be strip off and the worn or damaged coatings re-coated without changing part properties and dimensions; (v) Some spray processes can be moved on site, allowing spraying rapidly big parts, which displacement would otherwise be rather long and expensive.

Analysis of Temperature Variation in a Mild Steel Plate using LBM

LBM is a method used for the computations in dynamics of fluid by fluid simulation. In the present study, a square plate (Mild steel plate) of 10 mm X 10 mm dimensions has been selected. The temperature variation and heat flow at different nodes through the plate from its one end to another end would be simulated by giving heat from room temperature to 100° C in MATLAB software, C++ etc. After the simulation process, the results of temperature variation at different nodes will be shown on Tech-Plots in the form graphs b/w temperature and distance from one end of the plate to the another end of the plate.

Heart Disease Prediction System Using PCA and SVM Classification

Heart is the most significant part of human body. In this fast and busy life people eat what they want and diagnosis themselves. As a result they get sick and it results into heart failure. Life is completely dependent on the proper working of heart. If functioning of heart is not properly worked, it will also affect the other body parts of human body such as brain, kidney, etc. Heart Diseases are the major cause of deaths in the world. Various factors that increase the risk of Heart Diseases such as stress, cholesterol, high blood pressure, lack of physical exercise, smoking and obesity etc. The heart disease prediction system helps the physician and healthcare professionals as a tool for heart disease diagnosis. To protect the life of a patient from heart diseases there have to be quick and efficient prediction technique is to be followed. The main goal of this work is to develop an efficient heart disease prediction system using feature extraction and SVM classifier that can be used to predict the occurrence of disease. The prediction of heart disease pattern with classification algorithms is proposed here. Classification is one of the most important tasks in data mining. It is very essential to find the best fit classification algorithm that has greater accuracy on classification in the case of heart disease classification. This cleaned data is classified by the classification algorithms SVM classifier. This technique is widely used to validate the accuracy of medical data.
