Chapter 7, Problem 6P

In 2008, The US Environmental Protection Agency (EPA) registered copper alloys as an antimicrobial material and approved a number of public health claims related to copper’s ability to kill specific bacteria. One of these claims stated that when cleaned regularly, antimicrobial copper alloy surfaces would kill more than 99.9% of bacteria within 2 hours, and continue to kill more than 99% of bacteria even after repeated contamination. The ancient Egyptians used copper in various forms to sterilize wounds and preserve drinking water, and interest in the medicinal value of the material continued for generations. Interest and use dropped markedly in the 1930s, however, with the development of medicinal antibiotics. Recently, antibioticâ€�resistant bacteria have emerged, and the benefits of copper are again being recognized.

  1. Use the Internet or other information source to identify some of the health�related applications that are now emerging for copper and copper alloys. Select one such application and summarize its benefits.
  2. What might be some of the deterrents or limitations to the use of copper and copper alloys, or the conversion to them from other materials, such as stainless steel?

It is the combined action of chemical attack and mechanical wear as a consequence of fluid motion. stress corrosion intergranular corrosion erosion-corrosion uniform attack corrosion
Two 0.5-cm-diameter rods of 1020 steel (σts = 395 MPa) are to be joined with a silver braze alloy 0.025 cm thick (σys = 145 MPa) to produce one long rod. The ultimate strength of this brazed structure is found to be approximately 345 MPa. If it is necessary to reduce the diameter of the rods to 0.25 cm with no change to the braze joint itself, will the strength (in MPa units) increase, decrease, or remain the same? If it changes, by how much?
