Amorphous Nickel Spraying Powder NanoX of HV700-900, 1000℃ Erosion Resist  

Better than Hastelloy, Inconel, Stellite

1. Amorphous Nickel Spraying Powder of HV700-900, 1000℃ Better Erosion Resist than Hastelloy, Inconel, Stellite Description

AMTmetalTech patent Gas Atomized Powder NanoX and NanoY are Nickel Self-fluxing Alloy improved from Hastelloy. Both are of uniform Amorphous+Nanocrystalline microstructure, with sizes 8-25, 15-45, 2-10, 25-90um etc. Fine powder can be for Tube Inside ID coating and the finish is very smooth. After metal thermal spraying in some lower heat input than Tungsten Carbide powder and with rapid cooling, the Coating can achieve higher Amorphous rate than in the powder. The NanoX coating can have porosity lower than 0.1%, deposition rate about 50% and the coating of thickness over 50um can be no need sealing and very economic for replace chrome plating. The NanoY coating can have porosity about 1% and the deposition rate about 70%.

NanoX and NanoY Powder Sizes Choice: 

1.1 Size 8-25um is for various Guns of Axial or Center Direction powder feeding. 

1.2 Size 15-45um is for various Guns of Radial or Vertical Direction powder feeding. 

1.3 Size 2-10um is for Guns of Inside Diameter ID under 80mm tube inside coating. 

1.4 Size 25-90um is for Plasma or Detonation Spraying.

2. Amorphous Nickel Spraying Powder of HV700-900, 1000℃ Better Erosion Resist than Hastelloy, Inconel, Stellite Properties

2.1 better corrosion resist than Hastelloy C276 or Inconel625 and Stellite6 or 12, can resist pure Acid or pure Alkali. 

2.2 high hardness HV700-900 and have very good Erosion resist. 

2.3 can resist high temperature up to 1000℃. 

2.4 good bonding strength. 

2.5 can be used for HVAF or HVOF thermal spraying, Plasma or Detonation Spraying, act as Bond Coat or Tube Inside ID coating.

For further increase the abrasion or wear resistance, NanoYW=NanoY+15% （WC/10Co/4Cr）, NanoXW=NanoX+15%（WC/10Co/4Cr）

Thermal Spraying Process Suggestions:

A1 Choose suitable parameters by trial specimens before the salt fog test formal specimen. The microstructure of the trial specimens has to have the uniform lamina without big round particles and oxidizing. The hardness of the trial specimens has to be not too high.

A2 Use pressure air 50mm top from the coating for quick cooling out of the nozzles front and back of the spraying gun during spraying as above picture.

A3 Choose Short Barrel. Short Spraying Distance. Low Flame Temperature. Keep the base metal temperature under 100℃. Each pass thickness under 8um. When act as bond coat, the follow-up coating need quick cooling. Grinding or polishing the specimen to be metallic shiny before erosion or abrasion test.
