Materials are precious resources. Different methods are employed to protect the material from degradation. Thermal spraying is one of the most effective method to protect the material from wear, high temperature corrosion, stresses and erosion, thus increasing the life of material in use. Detonation gun spraying is one of the thermal spraying techniques known for providing hard, wear resistant and dense microstructured coatings. This paper summarizes the results of previous research done by various authors on different coatings done by detonation gun spraying technique.

全球化通常被人们称颂为人类自由的进步,因为在全球化社会里,个人能够更自由地根据自己的选择去生活.全球化的批评者们则认为,全球化意味着要强加给人们一系列共同的全球性标准,这些标准牵涉到权力的运用,这种权力能导致类似'王国'模式的形成.那么,我们应该如何理解全球化与'王国'之间具有象征性的共同点呢?我认为,用'网络权力'这一概念,可以解释全球化环境下的权力动态操纵方式.
