What is the nano in nano titanium plating?
What is the nano in nano titanium plating? Nano is the translation of the English namometer, is a unit of measurement in physics, 1 nanometer is one billionth of a meter; equivalent to the length of 45 atoms arranged. In layman's terms, it is equivalent to one ten-thousandth of a hairline. Like millimeters and micrometers, the nanometer is a concept of scale and has no physical connotation. When the material to the nanometer scale, about 1-100 nanometers in this range of space, the performance of the material will undergo a sudden change, the emergence of special properties. This kind of material with special properties different from the original composition of atoms and molecules, and also different from the macroscopic material composition, i.e., nanomaterials. If only the scale reaches nanometer, and there is no special properties of the material, also can not be called nanomaterials. In the past, people only pay attention to atoms, molecules or cosmic space, often ignoring this intermediate field, which actually exists in large quantities in the natural world, but only previously did not recognize the performance of this scale range. ** a really recognize its performance and quote the concept of nanometer is the Japanese scientists, they in the 1970s with the evaporation method to prepare ultramicro ions, and through the study of its performance found that: an electrically conductive, thermally conductive copper, silver conductor into the nanoscale, it will lose the original properties, showing neither conductive, nor thermally conductive. Magnetic materials are also so, like iron cobalt alloy, make it about 20-30 nanometer size, the magnetic domain becomes single domain, its magnetic properties than the original 1000 times higher. 80's, people formally named this kind of material as nanomaterials.
