How to Select the Right Anti-Wear Additive for Lubricants
Five Key Factors for Choosing Anti-wear Additives
Operating Conditions
Different equipment loads and temperature conditions determine the type of anti-wear additive to choose:
Low-load systems: Basic AW additives can be used.
Medium-high load systems: Compound or highly active additives are recommended.
Base Oil Type
Anti-wear additives must be highly compatible with the base oil system:
Mineral oil system: Wide applicability, lower cost.
PAO synthetic oil: Additives with better solubility are required.
Ester base oil: Polarity and compatibility need to be considered.
Environmental and Regulatory Requirements
With increasingly stringent environmental regulations, the demand for low-ash, phosphorus-free, and sulfur-free products is increasing:
Ash-free anti-wear agents: Suitable for environmentally friendly lubricants.
Low-phosphorus formulations: Suitable for engine oils and export markets.
Additive Synergistic Effects
Anti-wear additives are often used in synergy with the following additives:
Antioxidants, detergents and dispersants, extreme pressure additives.
Proper formulation can significantly improve overall lubrication performance.
Application Areas
Different application scenarios have different requirements for anti-wear additives:
Hydraulic oils: require excellent anti-wear and anti-oxidation properties
Engine oils: need to meet emission regulations (e.g., low phosphorus)
Gear oils: need to be used in conjunction with extreme pressure additives
Metalworking fluids: require good lubrication and cooling properties
