Corrosion of Nickel-Base Alloys

Nickel-base alloys represent critical materials in modern industry due to their exceptional ability to withstand severe operating conditions involving corrosive environments, high temperatures, and elevated stresses. Pure nickel's face-centered cubic crystal structure provides inherent ductility and toughness, while offering excellent corrosion resistance in atmospheric conditions, freshwater, and caustic alkalis.

Corrosion of Titanium Alloys: Part One

Titanium demonstrates exceptional corrosion resistance in severe environments, making it invaluable across multiple industries including chemical processing, energy, desalination, and military applications. The metal's most significant properties include immunity to pitting corrosion and stress corrosion cracking in chloride solutions. This protective capability stems from a stable, adherent oxide film that forms instantly upon exposure to air or moisture.

Corrosion of Titanium Alloys: Part Two

Titanium alloys demonstrate exceptional corrosion resistance in most environments, but specific corrosion mechanisms can still affect their performance under certain conditions. This article examines four primary corrosion concerns for titanium alloys: erosion corrosion, stress corrosion cracking, corrosion fatigue, and crevice corrosion.

Corrosion of Titanium and Titanium Alloys

Titanium alloys exhibit exceptional corrosion resistance properties due to the formation of stable, protective oxide films on their surfaces. Originally developed for aerospace applications in the 1950s, these materials have expanded into industrial sectors due to their high strength-to-density ratios and resistance to corrosive environments.

Corrosion of Zinc

This comprehensive article examines the corrosion behavior of zinc and zinc-based protective coatings in various environments. It details the mechanisms of zinc corrosion in atmospheric, aqueous, and chemical conditions, with particular emphasis on the formation of protective films that contribute to zinc's corrosion resistance. The article explores seven major zinc coating methods, including hot dip galvanizing, continuous-line galvanizing, and electrogalvanizing, discussing their industrial applications and comparative advantages.

Corrosion of Zirconium Alloys: Part One

Zirconium alloys are principally used in highly corrosive environments like nuclear reactors which have very specific conditions connected to the fuel burn up cycles and water chemistry.
Although corrosion resistance in these materials is superior, with adequate mechanical properties, and low thermal neutron cross-section, they are still prone in such harsh conditions to lifespan limiting corrosive forces.
