Description
Antiwear additives are essential components in lubricating oils designed to minimize wear and extend the lifespan of machinery components by forming a protective film on metal surfaces. These additives work by reducing friction between moving parts, preventing metal-to-metal contact, and thereby reducing wear, extending equipment life, and improving overall performance.
AW additives function primarily through a chemical reaction with the metal surface:
Reaction and Sacrificial Film Formation: When metal surfaces come into close contact and pressure increases, AW additives react chemically with the metal. This reaction forms a thin, sacrificial film on the metal surface. This film is designed to be slightly softer than the underlying metal and wear away gradually, protecting the actual engine component from direct contact and wear. Common AW additives include zinc dialkyldithiophosphates (ZDDP), a well-established and effective type.
Antiwear lube additives applications:Widely used in automotive engine oils, industrial gear oils, hydraulic fluids, transmission fluids, metalworking fluids and other high-performance lubricants.
When selecting an antiwear additive supplier, it’s essential to consider factors such as product quality, technical support, regulatory compliance, and sustainability.
Collaborating with experienced additive suppliers like Shanghai Minglan Chemical Co., Ltd. can help ensure that you have access to high-quality antiwear additives and comprehensive support to meet the specific requirements of your lubricating oil formulations across various applications.
