Abstract

Purpose. To evaluate the optimization of the process of gas-thermal spraying of polymer coatings modified with nanodiamonds. The research task was the choice of methods for applying polymer coatings, determined by the geometric parameters of the parts and products to be coated, their design and technological features, the conditions of future operation, and the required thickness of the functional polymer layer.

Methods. When developing a mathematical model for the process of gas-thermal spraying of a nanocomposite polymer coating for the purpose of determining optimal technological conditions, a multidimensional project synthesis method was used that takes into account the features of a real nanotechnological system. Finding. An effective method of increasing the physical, mechanical, and anticorrosion properties of applied coatings from metals, alloys, and plastics is their modification by nanoscale components.

Application field of research. The use of coating technology from thermoplastic polymers to protect against corrosion and wear is one of the effective ways to improve the durability of machine parts and structural elements. Coatings formed by dispersed polymers successfully replace paint, galvanic and obtained by gumming.

Conclusions. The experimental-statistical mathematical model of the process of gas-thermal spraying of a composite polymer-nanodiamond coating was developed where the following materials and structural and technological factors were adopted as control parameters (independent variables): modifier concentration in the initial polymer-nanodiamond powder composition (mass %), pressure (MPa), inflow distance (mm), coating thickness (μm). The optimization criteria (quality indi-cators) are the following coating characteristics: adhesion strength (MPa) and corrosion resistance (days).
