The objective of this work is to present a literature review of biodiesel studies and its behavior in contact with metallic materials. It is known that biodiesel is a biofuel that has been used around the world as an alternative to replace diesel. One of the advantages of biodiesel is that it is a great lubricator, increasing the performance and long life of the engine. The disadvantage of biodiesel is the lack of oxidative stability, causing wear problems in metals, materials that engines and storage tanks are made of, to suffer over time. The high costs of producing biodiesel is also a complicating factor in this type of energy. Currently, many works have been developed to find varieties of raw materials to reduce these costs, since 60-80% of the cost is with the raw material. The dissertation is based on a literature review using some systematic review tools. Representing a compilation of 33 scientific works that presented as results the articles published in the last 15 years relating the behaviour of biodiesel with metallic materials. The number of publications per year and the countries that published the most on the subject: Brazil and Malaysia stand out. Stratification of journals that published these articles. The temporal distribution of the metals used in the articles, one can observe the growing interest in metal alloys such as aluminium and steel alloys. Studies have presented as options the use of natural antioxidants as alternatives to the problem of oxidative stability of biodiesel.
