Aluminum Surface Finishing Corrosion Causes and

Oct 17, 2014Aluminum corrosion is commonly encountered when performing chemical process operations involving surface finishing, predominantly in preparation for paint application. The protective oxide film of aluminum is only stable in a pH range of 4.5 -8.5. However, many process solutions intentionally exceed this pH range for the purpose of cleaning

Silica, Crystalline

Crystalline silica is a common mineral found in the earth's crust. Materials like sand, stone, concrete, and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks, and artificial stone. Respirable crystalline silica – very small particles at

Choosing the Right Blast Media for Abrasive Blasting

When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils – thousandths of an inch.In the metric system, the micron(one millionth of a meter) is used.

Basic Pasture Management for the Equine Owner

Jul 05, 2013Gravel and sand can also be used, but horses should not be fed on sand, since it can cause colic and impaction if the sand particles are ingested. Pasture Renovation. There are two factors that greatly affect successful renovation: seed to soil contact and seeding depth. Planting seeds too deep is the #1 cause of forage seeding failure.

Causes and Remedies of Cracks in Concrete Buildings

Therefore, low permeability is a key factor to concrete durability. There are number of factors that controls concrete permeability like water-cement ratio, use of admixtures, curing, air voids due to deficient compaction, micro-cracks due to loading, cyclic exposure to thermal variations, and age of concrete.

How to Choose the Right Tool for Milling Titanium

Dec 12, 2003Milling titanium is like milling other hard-to-machine metals in that a small increase in cutting speed can lead to a big increase in edge wear. Milling titanium is different from other metals because of the risk of heat build-up. Thanks to the metal's low thermal conductivity, overly aggressive milling may even pose a risk of combustion.

Factors that Affect the Yield Strength of Metals

Factor # 2. Effect of Strain Rate: Another factor that increases load on forming equipment is the rate at which the forming process is carried out. At higher rates of strain the flow stress of material increases leading to higher loads on the equipment. The effect of strain rate on yield strength for an alloy is illustrated in Fig. 1.11.
