Burning 2

แปลว่า(english) Heating a metal beyond the temperature limits allowable for the desired heat treatment, or beyond the point where serious oxidation or other detrimental action begins.

Aging 2

แปลว่า(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.

Blister 2

แปลว่า(english) A defect in metal, on or near the surface, resulting from the expansion of gas in a subsurface zone. Very small blisters are called pinheads or pepper blisters.

Burnishing 2

แปลว่า(english) Smoothing surfaces through friction between the material and material such as hardened metal media.

Blowhole 2

แปลว่า(english) A cavity which was produced during the solidification of metal by evolved gas, which in failing to escape is held in pockets.

Abrasion 2

แปลว่า(english) The process of rubbing, grinding, or wearing away by friction.

แปลว่า(english) Natural – sandstone,emery,corundum,diamonds, or Artificial – silicon carbide,aluminum oxide – material used for making grinding wheels,andpaper,abrasive and lapping compunds.

Bronze 2
