No. in figure / part	Location of use	Coating in original data	Application purpose & items to check
01 Brake piston	Wheel brake	Ni-P	Wear resistance
02 Belt tensioner	Engine accessory belt	Ni-P	Wear resistance
03 Brake wheel cylinder	Wheel brake system	Ni-P	Wear resistance
04 Clutch hub	Manual transmission system	Ni-P	Sliding, wear resistance
05 Turbine rotor	Engine boost system	Ni-P	Magnetism descriptions in the original are inconsistent; to be confirmed
06 ABS accumulator assembly	Brake hydraulic control unit	Ni-P	Sliding, corrosion resistance; original part name to be confirmed
07 Carburetor	Conventional engine fuel supply system	Ni-P	Corrosion resistance; not a common configuration in modern vehicles
08 Differential gear washer	Inside the differential	Ni-P + PTFE	Sliding, noise reduction
09 Shift fork	Inside the manual transmission	Ni-P + SiC	Wear resistance
10 Roller bracket	Fuel injection control mechanism	Ni-P	Wear resistance, rust prevention, dimensional accuracy
11 Compressor wheel	Engine intake and exhaust systems	Ni-P	Hardness, corrosion and wear resistance; original EGR/turbocharging use to be confirmed
12 Aluminum impeller	A/C compressor mechanism	Ni-P-B	Sliding, hardness, wear resistance; vehicle-specific layout to be confirmed

Parts and coating directions are compiled from the original website application cases. Positions in the figure are reconstructed by system relationship; this does not mean any one vehicle model uses all these parts. Specific coated surfaces, dimensions, tolerances and thickness are confirmed per part drawing.

Application needs

Focus on wear, friction, corrosion and dimensional change of mating surfaces. Heat treatment may affect the substrate or coating; state any limits at the evaluation stage.

Part types open for discussion

Pistons, transmission parts, shafts and aluminum alloy sliding parts. This is an application evaluation direction and does not indicate that any specific customer project has been undertaken.

Prepare before evaluation

Mating material, lubrication conditions, load, temperature, heat-treatment limits, batch size and acceptance conditions.

From requirement to verification

1. Submit drawings stating the substrate, quantity and operating conditions.
2. Engineers check pretreatment, coating system, thickness and assembly requirements.
3. Arrange sample verification as needed, and confirm quotation and acceptance conditions.
