ตัวกรองผลการค้นหา
Broaching
แปลว่า(english) Smoothing machined holes or outside surfaces of castings by drawing pushing on or more broaches (special cutting tools) through the roughed out hole.
surface-tension
แปลว่าความดึงดูด ที่ทำให้ของเหลวกลายเป็นเยื่อบางจับรอบวัตถุ
Wagner Fineness
แปลว่า(Concrete Engineering) The fineness of materials such as portland cement expressed as total surface area in centimeters per gram as determined by the Wagner turbidimeter apparatus and procedure.
Blister
แปลว่า(english) 1) Coating defect consisting of the formation of bubbles in a coating, which appear as hemispherical elevations. The blisters are hollow, and are usually caused by entrapped air or solvent. 2) A raised spot on the surface on the surface of metal due to expansion of gas which causes a subsurface metal separation such as inclusions and small laminations.
surface tension
แปลว่าแรงตึงผิว
Bright Dipping
แปลว่า(english) Chemical polishing of aluminum, often by treatment with a mixture of nitric acid and phosphoric acid, yielding a mirror-shiny (specular) highly reflective surface. It is almost always followed by anodizing to protect the surface and provide some choice of color.
Bright Annealed Wire
แปลว่า(english) Steel wire bright drawn and annealed in controlled non-oxidizing atmosphere so that surface oxidation is reduced to a minimum and the surface remains relatively bright.
Brinell Hardness Testing
แปลว่า(english) Method of determining the hardness of materials; involves impressing a hardened ball of specified diameter into the material surface at a known pressure (10-mm ball, 500-kg load for aluminum alloys). The Brinell hardness number results from calculations involving the load and the spherical area of the ball impression. Direct-reading testing are generally used for routine inspection of forgings, and as a heat treat control function.
Nitrification
แปลว่า(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.
level surface
แปลว่าพื้นหน้าระดับเท่ากัน
Broach
แปลว่า(english) A long, tapered cutting tool with serrations which,when forced through a hole or across a surface, cuts a desired shape or size.
Change of State
แปลว่า(Concrete Engineering) The process whereby liquid is heated to the point of evaporation changing the liquid into a gas the condensation of a gas on a cooler surface returning it from gaseous to liquid form.
