    To prevent galvanic corrosion in iron and steel alloys, coatings made from zinc and aluminum are helpful. Large components, such as bridges and energy windmills, are often treated with zinc and aluminum corrosion resistant coatings because they provide reliable long-term corrosion prevention. Steel and iron fasteners, threaded fasteners, and bolts are often coated with a thin layer of cadmium, which helps block hydrogen absorption which can lead to stress cracking.

    What are the different types of equipments for the conveyance of solids? The various types of equipments available for the conveyance of solids are as follows: Gravity Chutes: This equipment relies on gravity for the solids to fall under. Air Slides: In this equipment the particles are suspended in air, and flow at an angle to the horizontal. Belt Conveyors: This equipments use a belt to transfer the solids. Screw Conveyors: The solids are moved using a rotating helical impeller. Bucket elevators: The solids are moved using buckets which are attached to a belt in motion. Vibrating Conveyors: The solid particles are subjected to vibrations and travel over to a table in a series of steps. Pneumatic/ Hydraulic Installations: The particles are transported over a stream of air or water.

    What are the merits of using a falling film evaporator? The advantages of using falling film evaporators are as follows: These types of evaporators have very high heat transfer coefficients ranging from 2000-5000 W/m(square) for water and 500 to 1000 for organic liquids The residence times are short in case of heated surfaces, 5-10 seconds without recirculation They have very low pressure drops, 0.2-0.5 kN/m(square) , These evaporators are well suited for vacuum operations as well. The evaporation ratios are very high. 70 per cent without and 95 per cent with recirculation, They have a very wide operating range, they can provide as much as 400% of the minimum throughput, In addition to the above advantages they have a low cost of operation and are less susceptible to fouling
