Titanium carbide (TiC) is silver-gray and offers high resistance to abrasive wear and cratering because of its increased hardness.
Tungsten alloys for barrel linings and screw hardfacings offer excellent protection against abrasive wear.
The most obvious abrasive wear occurs in the high shear areas of the mixing chamber, specifically where there is an obvious loss of metal on the leading edge of the rotor wing for a tangential mixer and on the minor and major diameters of the rotors of the intermeshing designs.
While there are many types of wear, tool engineers should be most concerned with adhesive and mild abrasive wear, which combine to cause billions of dollars in tool replacement costs every year.
Mold surface treatment helps with abrasive wear from the processing of the materials, provides corrosion resistance from chemical attacks by the various chemical ingredients and by-products from the curing process and provides a smooth, pore-free surface for part quality and reduced mold fouling.
Nanostructured coatings are up to four times more abrasive wear resistant and exhibit more than double the bond strength compared to conventional coatings.
Potassium hydroxide will dissolve in the oils and fats faster and stay dissolved longer than the sodium hydroxide, and at first would sound like the better choice of catalyst, but potassium hydroxide also creates problems with the final bio-diesel because it can create an excessive ash content in the burned fuel, and can lead to engine deposits and high abrasive wear on the pistons and cylinders.
Fortunately for most injection molds, seals are not required to withstand extremely high water pressures (usually only 45 to 60 psi), frictional heat, or abrasive wear.
Using high pressure air, it achieves higher solids-to-air ratios and minimizes degradation and abrasive wear by conveying slow moving, tightly packed material, according to the literature.
These steels provide an excellent combination of high resistance to abrasive wear and high-bend fracture strength, which make them the right choice for tools processing today's highly engineered resins.
Extensive in-vitro testing was conducted internally and in conjunction with independent laboratories to measure metrics such as resistance to abrasive wear, subluxation wear, oxidation, fatigue, and crack propagation.
