Total Seal Diesel Engine Pistons - Product

Other Specification : Total Seal Alloy Diesel Engine Pistons 4 Cylinder , Isuzu Engine Parts ISUZU PISTON 4JA1-98 8-97176-600-0 Piston Technology Tin Coating Tin Is Coated By Electro Analysis Or Heat Dipping At Thicknessbetween 0.001 And 0.003mm. Tin Is Characterized As Soft And Oil-friendly Which Improves Running-in Efficiency Of Piston And Liner. This Coating Is Most Commonly Used. Graphite Sprayed At Piston Skirt/Graphite Printing Graphite Is Characterized As Good Lubricating, Which Helps Lubricant Adhering To Coating Surface. The Coating Will Reduce Friction And Scratching. The Thickness Is Between 0.01and 0.02 Mm. Piston Roof Anodizing The Piston Roof Is Anodized By Electro Bath, Forming Thin Layer Of Al2O3 , This Treatment Will Improve Heat Resistance (above 500), Heat Conductivity And Anti-corrosion, It Helps Prevent Piston Roof Burn-up. The Thickness Is Normally 0.02 To 0.05mm. If The Thickness Increases By 0.01mm, The Heat Conductivity Will Decrease By 25%, The Roof Temperature When Running Will Belowerfrom 30 To 50. Anodizing Technology And Processing Is Normally Complicated. Piston Roof MoS2 Spraying The Function Is Close To Roof Anodizing Improving Heat Resistance. The MoS2 Is Also Good At Lubrication. (The Bigger Piston Below Is Piston Roof Anodizing, The Smaller One Is MoS2 Spraying) Phosphate The Phosphate Is Aimed To Improve Initial Running-in Performance. The Phosphate Layer Is Easy To Wear Off And Helpful To Improve Running-in. Ceramic Spraying The Treatment Performance Is Similar To Anodizing And Heat Insulation Performance Is Better. The Ideal Thickness Is 0.2 To 0.3mm. When Running Under High Temperature, The Ceramic Is Easy To Crack And Wear Off. It Is Not Commonly Used Due To High Cost A Piston Is A Component Of Reciprocating Engines, Reciprocating Pumps, Gas
