The SPR peak depends on the size, the shape, and the chemical environment of the metal NP, such that modifying one of these parameters represents a way to control the optical properties of the corresponding composite materials; i.e., a matrix containing metallic NPs.

Epoxy fickerts are the most used by the industry, and although they are technologically more advanced, they are composed of non-renewable materials that contain bisphenol A and epichlorohydrin, substances that may be potentially harmful to human health [3].
Methods and Materials The materials used to prepare the specimens were: the bicomponent polyurethane resin composed of 1.2:1.0 ratio of polyol and prepolymer, respectively; the silicon carbide (SiC) and the rice hull ash (RHA), to improve the abrasion resistance of the matrix, both in particle size of 1200 mesh.

Water dose to the best cooling effect must be equivalent to the amount of water that materials can vaporize and participate in the phase-change heat transfer under certain temperature.
So we need to build experimental platform such as: Simulation of the materials generating cutting heat continuously in practice cutting, feeding heat to one end of the test sample, cooling the other end of the test sample with different water density in cryogenic gas atomization jet cooling, and we should minimize the impact of environmental factors as far as possible , check the changes of the temperature real-timely and transmit it to the Data Acquisition Instrument.
Similarly , when at 500 ˚C, 650 ˚C on the nickel-base alloy test sample surface, 4ml/min and 6ml/min water dose can be all vaporized and processed phase-change heat transfer, it is indicated that the best heat transfer coefficient corresponding to materials and temperature must be found for getting the best heat transfer effect.
It is indicated that the water dose to the best cooling effect must be equivalent to the amount of water that materials can vaporize and participate in the phase-change heat transfer under certain temperature.
