Abstract: This review provides an outline of related literatures in which scientists and researchers used different types and procedure of corrosion inhibitors to reduce corrosion that takes place in various equipment made of alloys or metals. Different chemical inhibitors were used to reduce the rate of corrosion in various alloys. The inhibition rates ranged between 30-80% in acidic environments with different molar concentrations. The second part of this article, the laser was used as a tool to inhibit the corrosion of some alloys and under various conditions without used chemical inhibitors as an auxiliary agent. The effect of the laser pulses on the material leads to an increase in its hardness and thus its corrosion resistance. We found that the rate of inhibition reaches about 80%.
