Common engineering materials which produce the passive oxide film?

The most common engineering material I have worked with that forms a passive oxide film is Aluminum which forms the film when contacted with air. Some types of Stainless Steel can also be induced to form a passive oxide film by treatment with nitric acid. "Hot bluing" can be used to provide limited protection to other types of iron and steel by bathing them in hot aqueous solutions of potassium nitrate or sodium hydroxide to form a layer of magnetite (Fe3O4). Note that regular red rust is Fe2O3. "Rust bluing", "cold bluing" and carefully controlled heat treatment of iron and steel pieces can also be used to impart a protective oxide finish. All of these bluing processes still require additional treatment with oil to provide lasting protection.

Magnesium is another possibility.

Importance of sedi rocks in engineering geology?
Sedimentary rocks are often used as building materials in construction and engineering. The most common type of sedimentary rock is limestone.
Is material science a topic related to chemistry?
Materials science is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. This scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry. With significant media attention focused on nanoscience and nanotechnology in recent years, materials science has been propelled to the forefront at many universities. It is also an important part of forensic engineering and failure analysis. Materials science also deals with fundamental properties and characteristics of materials. Before the 1960s (and in some cases decades after), many materials science departments were named metallurgy departments, from a 19th and early 20th century emphasis on metals. The field has since broadened to include every class of materials, including: ceramics, polymers, semiconductors, magnetic materials, medical implant materials and biological materials (materiomics).
What other two materials other than lava that erupt from volcanoes?
Ash and pumice are common materials.
What materials attract dirt?
There are many materials that attract dust.But one of the most common is actually Stainless Steel.
What type of bonds are in common engineering materials?
Ionic
What is considered building blocks for engineering materials?
The most common materials that are used in engineering are the following: aluminum and copper alloys, other metals, plastics, ceramics, and composite materials.
Importance of sedi rocks in engineering geology?
Sedimentary rocks are often used as building materials in construction and engineering. The most common type of sedimentary rock is limestone.
Why is it important metal for engineering materials?
Steel and iron are most common but nickel and copper work to. They provide more stableness and are easy to deploy and detach.

Materials Engineer?
Materials engineering is the field of engineering concentrating on the research and development of materials for various industrial uses. They are typically involved in the production of materials that are used to make products that range from computer hardware to the composite materials in snow skis and compound bows. Materials engineers often specialize in working with a specific type of material; common classifications are those who work with semi-conductors, metals, ceramics, composites, and plastics. All of these engineers work with a specific material, or group of materials, with single goal being to create a material that fits a certain industrial requirement through manipulating the original material or by using advanced scientific means to combine several materials to make a new one. The latter strategy is known as composites. Composites have become one the largest fields of materials engineering due to the endless possibilities for creating new and useful materials. Recent developments in technology have greatly increased the efficacy of materials engineering. Engineers are now able to simulate materials on an atomic level through the use of computer technology. This allows scientists and engineers to experiment and theorize in ways that were never possible in the past. The minimum requirements to become a materials engineer are to earn a bachelor’s degree in materials engineering. It is also very common for engineers with degrees in another engineering concentration, such as mechanical or chemical engineering, to cross over into the field. Positions that require graduate degrees are more common in this field than any other due to the highly scientific nature of the materials science. The job outlook for the Materials engineer is expected to be good. Demand for materials engineers will increase with the more common use of engineered materials such as those produced by biotechnology and nanotechnology. Materials engineers earn starting salaries that are well above those that are for the average graduate of a bachelor’s degree program, but average amongst the engineering specialties. The average starting salaries for materials engineers are typically around $55,000 to $60,000. The average salary for a materials engineer is $73,000, with the lowest salaries paid in the fields being $50,000 and the most highly paid being more than $120,000.
