Materials science, also commonly known as materials engineering, is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This relatively new scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry. With significant media attention focused on Nano science and nanotechnology in recent years, materials science is becoming more widely known as a specific field of science and engineering. ... Many of the most pressing scientific problems that are currently faced today are due to the limitations of the materials that are currently available and, as a result, breakthroughs in this field are likely to have a significant impact on the future of technology.
When struck against a rock – typically, by a frustrated golfer trying to hit a ball out of the shrubs and weeds on the golf-course margin – the titanium coating can produce a shower of such sparks.
“The temperature of these particles can get up to around 3,000 degrees Fahrenheit,” Earthman said. “Titanium reacts violently with both oxygen and nitrogen in the air.”
