People make better materials to serve the people.
l Esthesia of material in products design In the reflection of humanization, product’s materials are shown in that we choose material in the cultural and aesthetic level and from the point of security and environmental adaptability.
For example, materials such as wood and bark will remind people of some classical stuff, an earthy and natural feeling will arise spontaneously.

Introduction Ceramic materials are provided with high strength, high hardness, they are high temperature resistant, corrosion resistance, abrasion resistance, so they have been used widely in the electronics industry, machinery, chemical industry, communications and other fields, however, the ceramic material is a kind of highly brittle material, its flexibility and processability are poor, which limit its further application of the ceramic material.
In order to play fully its performance, the advantages of ceramics and toughness of metal are connected, spraying ceramic coating on the metal’s surface is a great progress on materials research and development.
If sprayed n-WC/12Co coating materials using HVOF on low carbon steel substrate, in the thermal sprayed layer, the original residual stress mainly comes from the rapid cooling and the inconsistency of thermal expansion of the coating and the substrate.

Therefore, the construction of high-rise buildings and long span elements is gradually increasing and structural steels are considered as one of the best materials in terms of faster construction and higher quality.
The other method is based on the output from the fire engineering and science [2].
